"‘The gene does not lead,’ she says. ‘It follows.’"

The selfish gene is one of the most successful science metaphors ever invented. Unfortunately, it’s wrong.

Y Front Page Post

Indeed, at 6 million years of separation, the difference in [Y-chromosome] gene content in chimpanzee and human is more comparable to the difference in autosomal gene content in chicken and human, at 310 million years of separation.
It is commonly said that the Human and Chimpanzee genomes share 99% or more identical DNA. In a surprising development about to be published in Nature, the Y-chromosomes of these two species were found to share only 70% of their DNA, raising important questions about the mode and tempo by which speciation from a common ancestor occurred. This finding may point the finger at the evolution of different patterns of sperm-competition and mating practices within these two species.

The Beauty Race

Researchers have found that beautiful women have more children than their plainer counterparts and that a higher proportion of those children are female. Those daughters, once adult, also tend to be attractive and so repeat the pattern.

Darwin, extended

The "blind watchmaker" may not be as blind as we thought. A team of scientists at Princeton University discovers that organisms are not only evolving, they're evolving to evolve better, using a set of proteins to "steer the process of evolution toward improved fitness" by making tiny course corrections.

Lateral gene transfer and the history of life

Festooning The Tree Of Life. Carl Zimmer describes new research on lateral gene transfer which makes the Tree of Life look more like a Gordian Knot.

Humans are evolving rapidly

Humans are evolving more rapidly than in the distant past, according to a new study published in PNAS. "The massive growth of human populations has led to far more genetic mutations, and every mutation that is advantageous to people has a chance of being selected and driven toward fixation. We are more different genetically from people living 5,000 years ago than they were different from Neanderthals", says lead author John Hawks. [more inside]

The Dawkins FAQ.

The Dawkins FAQ. Interesting Q&A session about evolution, biology, genes, etc with an expert. Dawkins claims no final answer on the "gay gene" or a Darwinian explanation of homosexuality.

Challenging Darwin: Is sex really all about the genes?

Author challenges Darwin's theory of "sexual selection." To Darwin, mutations that don't enhance survival, like peacocks' tails, must be aids to attracting mates to pass on genes. Homosexuality, therefore, is to Darwin and the Christian-right both an unnatural aberration. But with ever growing evidence of homsexual behavior in animals, from bonobos to penguins, isn't it time that Darwin's theory get replaced?
