DNA template could explain evolutionary shifts
Rearrangements of all sizes in genomes, genes and exons can result from a glitch in DNA copying that occurs when the process stalls at a critical point and then shifts to a different genetic template, duplicating and even triplicating genes or just shuffling or deleting part of the code within them, said researchers from Baylor College of Medicine in a recent report in the journal Nature Genetics. The report further elucidated the effect of the fork stalling and template switching mechanism involved in some forms of copy number variation.

Fossilised pregnant fish was one of the first animals to have sex
this specimen is one of the earliest examples of a pregnant vertebrate and shows that internal fertilisation, or sex, started far sooner than previously thought.

BBC NEWS | Science & Environment | 'Spookfish' has mirrors for eyes
"In nearly 500 million years of vertebrate evolution, and many thousands of vertebrate species living and dead, this is the only one known to have solved the fundamental optical problem faced by all eyes - how to make an image - using a mirror," said Professor Julian Partridge, of Bristol University, who conducted the tests.

LRB | Jerry Fodor: Why Pigs Don’t Have Wings
...we are all a little crazy, and for reasons that Darwin’s theory of evolution is alleged to reveal. What’s wrong with us is that the kind of mind we have wasn’t evolved to cope with the kind of world that we live in.

Humans Have Spread Globally, and Evolved Locally - New York Times
Historians often assume that they need pay no attention to human evolution because the process ground to a halt in the distant past. That assumption is looking less and less secure in light of new findings based on decoding human DNA.

Study moves chimp-human split to 4 million years ago
Chimpanzees and humans split from a common ancestor just 4 million years ago -- a much shorter time than current estimates of 5 million to 7 million years ago, according to a study published on Friday.
