My Backyard Today



In a long line at an understaffed polling place. Been in line for an hour so far…

Update 1: Crap! After standing in line for over two hours we find we are in the wrong place.

Bummer…Hip Dysplasia

Thursday my dog started having trouble with his left rear leg and would not put any weight on it. Took him to the vet, turns out he has hip dysplasia. At this point, the prescription is losing 20 lbs (he weighs 91) and short walks. We will also be putting him on antinflammatories. The vet also mentioned Duralactin – which has something to do with hyperimmunized cow’s milk …said it was homeopathic so I doubt we will be using it. I’m thinking ice packs might help, also. Any advice from people dealing with this would be appreciated.


New Divergence Times For Humans, Chimps, And Gorillas

A new paper in PNAS gives new estimates for the gorilla, chimp, and human divergence times. The study looked DNA from 105 gorillas and 226 chimpanzees to estimate divergence times.

Here is the abstract:
Abstract Fossils and molecular data are two independent sources of information that should in principle provide consistent inferences of when evolutionary lineages diverged. Here we use an alternative approach to genetic inference of species split times in recent human and ape evolution that is independent of the fossil record. We first use genetic parentage information on a large number of wild chimpanzees and mountain gorillas to directly infer their average generation times. We then compare these generation time estimates with those of humans and apply recent estimates of the human mutation rate per generation to derive estimates of split times of great apes and humans that are independent of fossil calibration. We date the human–chimpanzee split to at least 7–8 million years and the population split between Neanderthals and modern humans to 400,000–800,000 y ago. This suggests that molecular divergence dates may not be in conflict with the attribution of 6- to 7-million-y-old fossils to the human lineage and 400,000-y-old fossils to the Neanderthal lineage.

At any rate can someone send me a copy?
