Fishy miscegenation

More cuckoo than cuckoos: mate two salmon, get a... trout! Just give the parents a sperm transplant. And the sperm stem cells work in females too:
...Injecting the male cells into female salmon sometimes worked, too, prompting five female salmon to ovulate trout eggs.... The stem cells were still primitive enough to switch gears from sperm-producers to egg-producers when they wound up inside female organs....

Boys like trucks girl like dolls, the SSSM takes another hit

Some 25 million years ago, humans and vervet monkeys diverged from a common ancestor. In very rough terms, perhaps one and a quarter million human generations, or five million vervet generations, have been brought forth upon the Earth since that common ancestor lived. Of course, many differences have evolved between humans and vervets in those 25 million years: among other things, human parents choose toys for their children; vervet parents do not.

But after all that time and genetic change, and despite studies attributing human children's toy preferences to adult stereotypes, a new study by Dr. Gerianne Alexander finds that vervet males, like human boys, prefer toy trucks and balls, while vervet females and human girls prefer dolls and toy cooking pots. What's more, the vervets play with the toys much as human children do: males roll trucks on the ground, females inspect dolls (apparently) for genitalia.

Like a subway map, for SNIPs

Pretty and pretty interesting: unrooted haplotype networks -- diagrams showing the relation and mutational distance between different sets of DNA, with haplotypes represented by circles proportional to haplotype frequency, joined by lines proportional to mutational difference between haplotypes -- in cichlid fish (on page 3 ) [pdf], in stone loach fish ( on page 3) [pdf], in lesser prairie chickens (on page 6) [pdf] and in a ring species! (on page 2) [pdf]

Are you keeping your backups too?

(A)bort, (I)gnore, (R)evert to Grandma's DNA A jaw-dropping revision to Mendelian inheritance: bad genes can be replaced from a secret ancestral stash. (The same researchers have previously mentioned other ways to get around Mendel.) Also, DNA gets a fake fifth letter.
