John Hawks
gregladen | April 19, 2012John Hawks is one of the nation's leading palaeoanthropologists, and has lately been working with ancient DNA, recent and earlier Human Evolution, and an interesting project that is a sort of casting call for extinct humans and their relatives.
Most of you know John from his famous Internet site called "John Hawks Weblog: Paleoanthropology, Genetics and Evolution." John is an associate professor of Anthropology at the University of Wisconsin, Madison, which is one of the better known and respected for this sort of research.

John Hawks, in his paleodreams. I mean that in the best way.
John Hawks bumps into a prescient estimate of the total gene number in humans:
While doing some other research, I ran across a remarkable short paper by James Spuhler, "On the number of genes in man," printed in Science in 1948. We've been hearing for the last ten years how the low gene count in humans -- only 20,000 or so genes -- is "surprising" to scientists who had previously imagined that humans would have many more genes than this. So here's the next to the last line of Spuhler's article: On the basis of these speculations…

Early homind skulls, from A Kansan's Guide to Science (seriously)
A couple weeks ago, the Guardian ran an article in which Oxford neurobiologist Colin Blakemore described "how the human got bigger by accident and not through evolution." Though I didn't get to it at the time, I thought that an odd headline, since evolution actually occurs when genetic accidents -- those mutation things -- grant an advantage. Now John Hawks has written a post addressing what he says is a pretty big muckup by Blakemore:
Thanks to Jerry Coyne, I encountered an interview in the Guardian with Colin Blakemore…

from a different Daily Dish -- 365 petri dishes, by Klari Reis
House of Wisdom, the splendid new blog on Arabic science from Mohammed Yahia, editor of Nature Middle East describes an effort to map the Red Sea's coral reefs with satellite, aerial, adn ship-based technologies. Nice project and a promising new blog.
Brain and Mind
Ritalin works by boosting dopamine levels, says a story in Technology Review, reporting on a paper in Nature Neuroscience. The effect is to enhance not just attention but the speed of learning.
As several tweeters and bloggers have noted, H-Madness is a new group blog…

Savage Minds (with a spiffy website redesign) asks Why is there no Anthropology Journalism?
Jerry Coyne takes sharp exception to both a paper and a SciAm Mind Matters article by Paul Andrews and Andy Thomson arguing that depression might be an evolutionary adaptation. Dr. Pangloss punches back. (NB: 1. I was founding editor of Mind Matters, but no longer edit it, did not edit the Andrews/Thomson piece, and don't know any of these people. 2. While my recent Atlantic article presented an argument for how a gene associated with depression (the so-called SERT gene) might be…

Notables of the day:
John Hawks ponders the (bad) art of citing papers you've never read.
Clive Thompson ponders the new literacy spawned of engagement with many keyboards.
A poll on public education shows how much opinion depends on framing, context -- and who else thinks an idea is good. In this case, people liked the idea of merit pay more if told Obama likes it.
Mind Hacks works the placebo circuit.
And Effect Measure weighs in on the weird contrasts and (limited) parallels between swine flu and avian flu.
And for fun, fire lookout towers, from BLDGBLOG. You…
