The theory of evolution by natural selection was first formulated in Darwin’s book “On the Origin of Species” in 1859. It describes how organisms change over time as a result of changes in heritable ...

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 study published in Nature Ecology & Evolution reveals that the diversity of nonribosomal peptides, a class of compounds ...

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 ...

A 2026 study in two insect-pathogenic bacterial genera found that selection, genetic drift and biased recombination jointly ...

"Only strong men leave descendants. If that repeats, won't they eventually go extinct?"I read an online discussion with that ...

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

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 ...

Many of the most potent antibiotics originate from bacteria. A large proportion belong to a class of compounds known as ...
