Common features of domestic animals suggest caveats to evolutionary theory

White patches on fur coats, floppy ears, and curly tails are some of the traits frequently seen in domesticated animals. A group of researchers has now put forth a theory as to why these traits so often evolve in association … Continue reading

Smarter birds speciate faster

Evolution favors brainier birds. The most crowded branches of the avian tree of life generally hold the most intelligent birds because larger-brained birds split into new species faster than smaller-brained ones, according to recent work published in Evolution. “Being smart … Continue reading

By separating life stages, metamorphosis may circumvent harmful evolutionary tradeoffs

  There’s no guarantee evolution will bestow the best version of every trait. The benefits of one trait may impose a cost when an unfavorable trait, correlated genetically, comes along for the ride. In a recent study on wood frogs (Rana sylvatica) … Continue reading

Journal Club: Butterflies get diversity boost from associations with ants, plants

Harvard University evolutionary biologist Naomi Pierce began studying Lycaenidae butterflies as a graduate student in the 1980s. But only recently has she accumulated enough data, from her team’s work and others’, to begin to address the question that has long … Continue reading

Journal Club: Fruit fly hybrids make poor foragers, offering insight into how species remain distinct

  When one fruit fly species meets another, they sometimes interbreed. And yet despite this genetic mixing, distinct species still persist—over 2,000 of them. Evolutionary biologist Daniel Matute of the University of North Carolina at Chapel Hill is one of … Continue reading

Journal Club: Animals that glow for courtship have more species

The distinct blinking pattern of fireflies enables mate recognition and, thus, the perpetuation of the species. But it seems this flashy courtship ritual could be driving the formation of new species, too. A new analysis of diverse animal lineages—from octopuses … Continue reading
