Paper: So many exceptions to sex chromosome evolution

From the paper:
“Finally, the remarkable turnover of sex chromosomes in many systems, as well as variation in the rate of sex chromosome divergence, suggest that assumptions about the inevitable linearity of sex chromosome evolution are not always empirically supported, and the drivers of the birth-death cycle of sex chromosome evolution remain to be elucidated. ”

Researchers: When mates are rare, birds help their parents raise more offspring

Male birds are more likely to do so: After a five-year experiment, researchers from Florida State University and the Tallahassee-based Tall Timbers Research Station found that when fewer mates were available for brown-headed nuthatches, these small pine-forest birds opted to stay home and help their parents or other adults raise their offspring… Associate Professor of Read More…

NYT: Beauty in nature acknowledged — but only as “Darwin’s neglected brainchild”

The biggest problem, which Jabr discusses, is whether beauty really exists or is it just an illusion that promotes our genes’ survival, as a naturalist (nature is all there is) must insist. Yet, despite the stale “Darwin himself” creedal statements, the long piece ends on a curiously tolerant, ecumenical note.

Rob Sheldon on the failure of selfish gene theory in peacocks, as well as bees

Our physics color commentator Rob Sheldon writes to offer some thoughts on the recent study of bees, which failed to confirm selfish gene thinking as an explanation for communal life: This is really a most interesting study. If you recall, E. O. Wilson got fame and glory for studying ants. The problem he addressed, is Read More…

Evolutionary psychology explains why men pay on the first date. And don’t.

Explains everything and its opposite! Our philosopher and photographer friend Laszlo Bencze writes to apprise us of “the definitive explanation” of why men want to pay on a first date: “There is an evolutionary reason for this, says Helen Fisher, a biological anthropologist and senior research fellow at the Kinsey Institute at Indiana University Bloomington.

Replication failures of Darwinian sexual selection openly discussed at The Scientist

It’s as if evolutionary biologists are beginning to take some of the problems of Darwinism seriously enough to discuss them openly, as failures in research. In this case, the failure of claims for sexual selection (females drive evolution by choosing the fittest mates) are openly publicized. In the past five years, meta-analyses and reviews have Read More…
