Scientist at Work: Virginia Vitzthum

Vitzthum image Life is all about tradeoffs, judging prospective investments by their risks and rewards, and an Indiana University evolutionary anthropologist has shown this to be true at the very beginnings of life: When costs outweigh benefits, successful pregnancies are less likely to occur.  Full Story

Speciation through genome duplication more common in plant evolution than previously thought

Hexaploid fern

Extra genomes appear, on average, to offer no benefit or disadvantage to plants, but still play a key role in the origin of new species, say scientists from Indiana University Bloomington and three other institutions in the Aug. 10, 2009, issue of the Proceedings of the National Academy of Sciences.

Scientists find a common link of bird flocks, breast milk and trust

Zebra finches

What do flocks of birds have in common with trust, monogamy, and even the release of breast milk? According to a new report in the journal Science, they are regulated by virtually identical neurochemicals in the brain, known as oxytocin in mammals and mesotocin in birds.

After dinosaurs, mammals rise but their genomes get smaller

Michael Lynch

Evidence buried in the chromosomes of animals and plants strongly suggests only one group -- mammals -- have seen their genomes shrink after the dinosaurs' extinction. What's more, that trend continues today, say Indiana University Bloomington scientists in the first issue of a new journal, Genome Biology and Evolution.

Parasitic worms make sex worthwhile

New Zealand mudsnail

The coevolutionary struggle between a New Zealand snail and its worm parasite makes sex advantageous for the snail, whose females favor asexual reproduction in the absence of parasites, say Indiana University Bloomington and Swiss Federal Institute of Technology biologists in the journal Current Biology.
