The movement of genetic material between organisms that aren't directly related is a significant driver of evolution, ...

The microscopic alliance between algae and bacteria offers rare, step-by-step snapshots of how bacteria lose genes and adapt to increasing host dependence. This is shown by a new study led by ...

It is a prime example of natural selection, the evolutionary process by which organisms adapt to their environments to survive longer and produce more offspring.

Instead, the research suggests a nuanced evolutionary process, unfolding gradually over an extended period, with changes occurring at various times.
