Pre-Whales

29 07 2010

a.k.a. Pakicetidae:

Pakicetidae, Coyote, Pakicetidae.

“Pakicetids or Pakicetidae are a carnivorous mammal family of the suborder Archaeoceti which lived during the Early Eocene to Middle Eocene (55.8 mya—40.4 mya) in Pakistan and existed for approximately 15.4 million years.[1]

“As Cetacea, Pakicetidae precede the whales and dolphins in transition from land. Because their fossils were found near bodies of water, they are presumed to have spent part of their life in water.

“Pakicetus was the first discovered in 1983 by Philip Gingerich, Neil Wells, Donald Russell, and S. M. Ibrahim Shah, and all species are known only from a few sites in Pakistan, hence the name of the first genera and the family as a whole. The region is believed to have been coastal to the Tethys Sea when the pakicetids lived, some 53 million years ago.

“The pakicetids are presumed to be ancestors of modern whales because of the three following features unique to whales: peculiarities in the positioning of the ear bones within the skull, the folding in a bone of the middle ear, and the arrangement of cusps on the molar teeth. The current theory is that modern whales evolved from archaic whales such as basilosaurids, which in turn evolved from something like the amphibious ambulocetids, which themselves evolved from something like the land-dwelling pakicetids.”

The Great Pleasure

26 07 2010

“Learning is perhaps the only pleasure that might replace increasing consumption as our chosen mode of enriching experience. Someday, the joy of recognizing a pattern in a leaf or the geological strata in a cliff face might replace the satisfactions of new carpeting or more horsepower in an engine, and the chance to learn in the workplace might seem more valuable than increased purchasing power or a move up the organizational chart. Increasing knowledge of the ethology of wolves might someday replace the power savored in destroying them.”

- Mary Catherine Bateson, quoted in Courage and Calling by Gordon T. Smith.

I love learning, was filled with an insatiable curiosity from the moment (according to my mum) I opened my eyes. In my home country, people would never ask me a question like, “Why did you choose to go to Harvard?” – our attitude in Singapore is that you don’t choose Harvard – Harvard chooses you. If you get into Harvard, you’d better jolly well go. Not that I didn’t fret over it though – I was a little insecure and intimidated, wasn’t sure whether I’d thrive in a cutthroat environment, etc, etc, but really those were fears that were quickly overruled, and very soon the little envelope was mailed back and I started to prepare myself for the adventure that would be attending the Big H. Sure, I do still kind of suffer from the occasional useless counterfactual, but five years later, I have a fistful of regrets but a large sloshing bucket of gratitude.

I guess I’m revisiting my decision because the question resurfaced again this past month, when I was traveling in the Midwest, while staying with some family friends in Indiana.

When I first got to Harvard, I realized immediately it wasn’t the place I had thought it would be – in both good and bad ways. But because it was freshman year, I guess, and because I was suffering from a good dose of culture shock, at first it seemed primarily bad. To me the name of Harvard always called to mind the Ideal University – that is, the best university in this world and age, and therefore desirable in and of itself. It didn’t matter what its underlying principles were; or even who its faculty were. The very fact that it was the best meant it was some kind of platonic University, where all truth and knowledge of the ancients and the accumulated wisdom of the world today resided.

So, I used to be the girl with the 10 year plan. I was insatiably ambitious. When I was 7 or 8, I asked my elders and teachers what the best university in the world was (at the time, they answered “Oxford or Cambridge”), and decided then and there that I would work my ass off to get there. I don’t think I was primarily motivated by arrogance; when I was 7 I had barely any notion of ranking. In fact I was bizarrely innocent of the fact that my good grades meant that I was ranked highly against my peers – I had not made the connection between doing well and “winning” in some sort of race against everyone else. I guess my parents had taught me well not to compare myself with others. Of course, the moment the school rankings were published at the bottom of our report cards my innocence was completely and ruthlessly shredded to bits.  But my point is, I didn’t aspire to go to the best university because I thought I was the best – I aspired to go to the best university because it was the best.

Of course, I was disappointed. You see, I had always imagined universities to be beautiful floating islands with ivory towers and turrets in the clouds, where knowledge was pure abstraction, freed from the dross of the quotidian. I thought of professors as rootless sages, repositories of knowledge, without interfering backgrounds or personal tics that may bias them towards one field or opinion rather than the other. I don’t know where I got that idea – perhaps I thought my small country was provincial, and that in the big countries history was taught differently, or that with a full breadth of literature (or at least the Western canon) at my feet, I would have a better grasp of human nature than from 6 literature texts for the ‘A’ levels. I was actually stunned when I realized that in the department I was interested in, the best professors were Americanists, that they all approached their fields from personal interests (I was bewildered why black professors were teaching African American studies rather than being part of the history or literature departments) rather than from some Archimedean fulcrum from which they could leverage the world. I didn’t understand why Asian American writing had to be taught by Asians, why the Shakespeare professors were white, or why I had an American Literature requirement to fulfill. I was pretty devastated, actually.

Until I realized that there was no such university as the one I had been pursuing – that there is no objective standpoint to all knowledge, at least not one which any one human being can teach. And that there IS no objective standpoint that one can arrive at, either, no matter how good a student. And that the question, “Why did you choose Harvard?” is a totally valid one. I chose Harvard because I wanted to learn, and to learn from the best. I chose English because it was my comparative advantage, and also my passion. I chose to stick it out because too many people had invested in me, from the scholarship boards to my parents to my schools to my peers to my country, for me to just quit when the going got tough. I wasn’t just representing myself here – there was all this honor at stake.

There were people in my church who warned me against going to university to study literature because I would “lose my faith”. I was so annoyed I didn’t even answer them, I just smiled and nodded. But in my heart the remark stung, and I vowed to myself, if literature makes me lose my faith, then it wasn’t a faith worth having. Because, ironically, literature has, on more than one occasion, saved my faith. And because being put through the gigantic ego-wringer that is Harvard has been more purging, more cleansing of my soul than any other institution could possibly have been. The most important thing I learned in Harvard, in fact, was that I could hold a deep-seated, decades-old belief with all the intense fury I could muster, and still be wrong. I still remember, when I was faced with fulfilling my Science B (biology/chemistry) requirement, tiptoeing rather shamefacedly into the “Human Evolution” class for the introductory lecture, wondering if my church auntie was right. She wasn’t. I didn’t end up taking that class because I was too chicken, but I ended up taking Steven Pinker’s Human Mind class, which had a lecture on evolution. It was one of the most enlightening moments of my young life. I felt like the scales were falling off my eyes.

All my life when I picked up the children’s encyclopedias that lie around the house, and stared at the ethereal pictures of the planets in them, I was struck by their beauty and wonder. And then I would look at the dates scientists had labeled on them – however many billions of years, and I would be repulsed by what I thought was a lie, constructed by (what must have been) the infernal conspiracy of world scientists which I had learned about in church, to deny God’s creation. (Yes, I was surrounded by young earth creationist propaganda in my childhood). It bewildered me how the noble white-coated scientists of my imagination, whose science and technology had put a man on the moon, could simultaneously concoct such lies to fool small children, when they daily gazed through telescopes to see such heavenly beauty. It did not make sense to me, and now I see why.

I used to camp with my friends on the offshore island of Pulau Ubin, and, away from the light pollution of the mainland, we would gaze at the stars. What we saw was probably a pale imitation of the skyscape that our earliest ancestors gazed at – the skyscape that inspired myth, mathematics, astronomy, exploration, philosophy -  but still, no matter how diminished, there is still something awe-inspiring about seeing light that has traveled so far, light that is so old. Those massive balls of fire are lightyears away – I’d think to myself – billions of billions of lightyears away….They are signals sent from the dark of the deep past, beyond history, beyond mythology, into the retina of the now, from stars that may have long burned out, but which retain, for this split second, in my perception, their luminescent fury. And it just would not latch into place with my idea of a God who is just and constant and beautiful and, above all, True, to mislead his people each and every night with paper-thin lies, lies that those stars were not in fact more ancient than the earth, more ancient than human memory. It was hypocrisy to call God true and then accuse him of purposely setting the earth up to look old when it was in fact new. It seemed like a nonsensical concept to me, and for the longest time it gnawed in the corner of my brain, a thing I refused to think about, as I repeatedly pushed it out of my mind.

But now that I’ve looked it full in the face, I see that it is not so terrible – that in fact a God who used evolution to make us is an even more logical, beautiful, consistent and terrifying God than the one the pages of creationist magazines contained. I guess the moment of truth came to me when I had finished Jerry A Coyne’s amazingly respectful, mild-mannered “Why Evolution is True”, and I walked into the Northwest Labs building for the first time and saw, hanging above me, a gigantic, mysterious skeleton. It could have been a dinosaur, or some sea-monster of Nessie proportions. But then I saw below its ribcage two tiny, unconnected bones, precariously held in place by wire, that (I imagined) must have floated in the midst of fatty flesh and blubber when this creature still roamed the seas and I thought to myself, it must be a whale. Because Coyne had explained in his book the mysterious case of the whale – descendants of land mammals who returned to the water, thus leaving vestigial, unconnected pelvis and hindlimb bones beneath its spine. “Those bones serve no function at all, ” I thought. “It must be the skeleton of a whale.”

Two weeks later, the curators of that space finally put up a plague for the skeleton, and sure enough, it was.

And in that moment, my heart leaped and something latched into place.

For the Splendor of Creation – Gustav Holst’s The Planets

adapted for Harvard Commencement

For the splendor of creation that draws us to inquire,

For the mysteries of knowledge to which our hearts aspire,

For the deep and subtle beauties which delight the eye and ear,

For the discipline of logic, the struggle to be clear,

For the unexplained remainder, the puzzling and the odd:

For the joy and pain of learning, we give you thanks, O God.

For the scholars past and present whose bounty we digest,

For the teachers who inspire us to summon forth our best,

For our rivals and companions, sometimes foolish, sometimes wise,

For the human web upholding this noble enterprise,

For the common life that binds us through days that soar or plod:

For this place and for these people, we give you thanks, O God.

The Church of England’s posthumous apology to Darwin:

Charles Darwin: 200 years from your birth, the Church of England owes you an apology for misunderstanding you and, by getting our first reaction wrong, encouraging others to misunderstand you still. We try to practice the old virtues of ‘faith seeking understanding’ and hope that makes some amends. But the struggle for your reputation is not over yet, and the problem is not just your religious opponents but those who falsely claim you in support of their own interests. Good religion needs to work constructively with good science – and I dare to suggest that the opposite may be true as well

Plan A: Marriage, Not Polygamy

24 07 2010

Not Ideal.

image source

Then Jacob said to Laban, “Give me my wife, for my days are fulfilled, that I may go in to her.” … Now it came to pass in the evening, that he took Leah his daughter and brought her back to Jacob, and he went in to her. And Laban gave his maid Zilpah to his daughter Leah as a maid. So it came to pass in the morning, that behold, it was Leah. …Then Jacob… fulfilled her week. So he gave him his daughter Rachel as wife also. And Laban gave his maid Bilhah to his daughter Rachel as a maid. Then Jacob also went in to Rachel, and he also loved Rachel more than Leah. And he served with Laban still another seven years.

When the LORD saw that Leah was unloved, He opened her womb; but Rachel was barren. So Leah conceived and bore a son, and she called his name Reuben [literally, 'See, a son']; for she said, “The LORD has surely looked on my affliction. Now therefore, my husband will love me.” Then she conceived again and bore a son, and said, “Because the LORD has heard that I am unloved, He has therefore given me this son also.” And she called his name Simeon [Literally, 'Heard']. She conceived again and bore a son, and said, “Now this time my husband will become attached to me, because I have borne him three sons.” Therefore his name was called Levi [Literally, 'Attached']. And she conceived again and bore a son, and said, “Now I will praise the LORD.” Therefore she called his name Judah [Literally, 'Praised']. Then she stopped bearing.

Now when Rachel saw that she bore Jacob no children, Rachel envied her sister, and said to Jacob, “Give me children, or else I die!” And Jacob’s anger was aroused against Rachel, and he said, “Am I in the place of God, who has withheld from you the fruit of the womb?” So she said, “Here is my maid Bilhah; go in to her, and she will bear a child on my knees, that I also may have children by her.” Then she gave him Bilhah her maid as wife, and Jacob went in to her. Then Rachel said, “God has judged my case; and He has also heard my voice and given me a son.” Therefore she called his name Dan [Literally 'Judge']. And Bilhah conceived again and bore Jacob a second son. Then Rachel said, “With great wrestlings I have wrestled with my sister, and indeed I have prevailed.” So she called his name Naphtali [Literally, 'My Wrestling'].

When Leah saw that she had stopped bearing, she took Zilpah her maid and gave her to Jacob as wife. And Leah’s maid Zilpah bore Jacob a son.Then Leah said, “A troop comes!” So she called his name Gad [Literally, 'Troop' or 'Fortune']. And Leah’s maid Zilpah bore Jacob a second son. Then Leah said, “I am happy, for the daughters will call me blessed.” So she called his name Asher [Literally, 'Happy'].

Now Reuben went in the days of wheat harvest and found mandrakes in the field, and brought them to his mother Leah. Then Rachel said to Leah, “Please give me some of your son’s mandrakes.” But she said to her, “Is it a small matter that you have taken away my husband? Would you take away my son’s mandrakes also? And Rachel said, “Therefore he will lie with you tonight for your son’s mandrakes.”

When Jacob came out of the field in the evening, Leah went out to meet him and said, “You must come in to me, for I have surely hired you with my son’s mandrakes,” And he lay with her that night. And God listened to Leah, and she conceived and bore Jacob a fifth son. Leah said, “God has given me my hire, because I have given my maid to my husband.” So she called his name Issachar [Literally 'Hire']. Then Leah conceived again and bore Jacob a sixth son. And Leah said, “God has endowed me with a good endowment; now my husband will dwell with me, because I have borne him six sons.” So she called his name Zebulun [Literally, 'Dwelling']. Afterward she bore a daughter and called her name Dinah. Then God remembered Rachel, and God listened to her and opened her womb. And she conceived and bore a son, and said, “God has taken away my reproach.” So she called his name Joseph [Literally, 'He will add'], and said, “The LORD shall add to me another son.”

Genesis 29:29 – 30:24

It seems to me that when self-professed Christians who express nostalgia for a “golden age” world order somewhere in the distant past, who advocate for a return to “Old Testament morality”, they display a profound misunderstanding of genre. The passage above, for example, is a historical narrative (not Rankian History as we know it today, but rather history when history and literature were not too different from each other). History is not the same as Law: Genesis is descriptive of a certain society at a certain point in human history, and not a prescriptive recommendation for building the ideal society. Just because polygamy was present in the days of the patriarchs doesn’t mean that it made God happy – on the contrary, almost every instance in which polygamy occurs in the Old Testament ends in strife and division.

Slate on The Flooded Earth

detail of bookcover of The Flooded Earth, from Slate

In his new book, “The Flooded Earth: Our Future in a World Without Ice Caps,” Peter D. Ward, a professor of biology and earth and space sciences at the University of Washington, takes a look at what the latest predictions in sea rise will mean for the future of human civilization. In the coming decades, he argues, vast swaths of agricultural land will be ruined by encroaching salt water; the increasingly ice-free lands of Greenland and Antarctica will become contested and ever-more valuable, and our coastal cities’ spiraling preservation costs will bleed our economies dry. The book is a beautifully written, thoroughly research and relentlessly terrifying work, and a must-read for anybody with an interest in the environment or the future of our planet.

Salon spoke to Ward over the phone from Seattle about the world’s most threatened regions, the future of New York, and why the 21st century will belong to Canada.
