Molecular evolutionary biologist Masatoshi Nei says Darwin never proved natural selection is the driving force of evolution — because it isn't. In a cavernous concert hall, before an eager audience of ...

A new PNAS study finds identical genetic changes independently evolved in jellyfish lineages separated by more than 600 ...

While attempting to dismiss evidence for observed evolution, the creationist turns to birds whose beaks differ depending on ...

Natural selection is usually understood in the context of change. When organisms deviate from the norm, they may gain advantages that let their lineages outlast those of their less-adaptable relatives ...

Much change is due to random genetic drift rather than positive selection. It could be called the survival of the luckiest. You might think that largely neutral mutations would remain restricted to a ...

Natural selection is usually understood in the context of change. When organisms deviate from the norm, they may gain advantages that let their lineages outlast those of their less-adaptable relatives ...

Depending upon how you do the counting, there are around 9 million species on Earth, from the simplest single-celled organisms to humans. It’s reassuring to imagine that complex bodies and brains like ...

Scientists have identified a new member on the genetic family tree of an endangered pupfish native to south-central New Mexico. "We went into this thinking that there was one species of conservation ...

READER QUESTION: If humans don’t die out in a climate apocalypse or asteroid impact in the next 10,000 years, are we likely to evolve further into a more advanced species than what we are at the ...
