Funk That Macaque

Since I let my Science subscription lapse some time ago (not enough hours in the day, alas), it didn't occur to me that the recently-published Macaque genome might be available online. But in a nod to open access, Science has put together a special online collection around the subject.

The Macaque is important because it's only the third primate genome to be sequenced - the other two being the chimpanzee and humans. Its sequencing will allow all kinds of genomic triangulation to be performed to work who did what first in terms of genes and suchlike. It's also important because it represents at least one more such primate that we've managed to sequence before driving to extinction (hello gorilla, goodbye gorilla....)

Open Genomics, Closed Minds

One of the great things about open genomics - or bioinformatics if you prefer its traditional name - is that it provides a completely objective resolution of all sorts of emotional disputes.

For example, by feeding genomic sequences of various organisms into a computer program, you can produce a tree of life that is remarkably similar to the ones proposed by traditional evolutionary biology. But in this case, there is no subjective judgement: just pure number crunching (although it's worth noting that the trees vary according to the depth of the calculations, so this is not absolute knowledge, only an ever-closer approximation thereto).

Another case in point is the closeness of the relationship between the great apes and humans. Indeed, it is only human arrogance that allows that kind of distinction to be made: a computer would lump them all together on the basis of their DNA.

Against this background, it's surprising how much we naked apes cling to our difference from the hairy kinds: perhaps it makes us feel a little better in the face of the genocide that we are waging against them. However, it looks like things here might be changing at last:


He recognises himself in the mirror, plays hide-and-seek and breaks into fits of giggles when tickled. He is also our closest evolutionary cousin.

A group of world leading primatologists argue that this is proof enough that Hiasl, a 26-year-old chimpanzee, deserves to be treated like a human. In a test case in Austria, campaigners are seeking to ditch the 'species barrier' and have taken Hiasl's case to court. If Hiasl is granted human status - and the rights that go with it - it will signal a victory for other primate species and unleash a wave of similar cases.

...

One of their central arguments will be that a chimpanzee's DNA is 96-98.4 per cent similar to that of humans - closer than the relationship between donkeys and horses.

Sadly, there's a terrible race here: which will we see first - apes recognised as near-equals, or apes razed from the face of the earth? (Via Slashdot.)
