New method reveals how differences in the genetic “instruction booklet” between humans and Neanderthals influenced traits
Oct. 7, 2019—When it comes to our differences from Neanderthals, most of what we know comes from comparing fossils. But fossils can only tell us about bones and not whole living organisms. That’s changing thanks to a new paper from a team of genomics researchers at Vanderbilt, who have developed a first-of-its-kind computational method. Their approach uses...

How attracting multiple mates affects flirting fads in birds
Feb. 22, 2019—For many species, extravagant displays are a critical part of attracting a mate. Think of a peacock’s long tail or a songbird’s elaborate melody. When considering these populations, scientists at Vanderbilt University wondered if they could use new methods to test a theory that has been around for almost 150 years: that having multiple reproductive...
