It’s time to give the violent metaphors of evolution a break. For those most invested in the old-school Darwinian view of the survival of the fittest and violence as virtue, then, the message is clear: Just relax.
New mothers show evidence of neural remodeling up to two years after giving birth
Just like taxonomists have debated over which physical characteristics warrant a new species designation, they’re conflicted over how much genetic variation you need to prove differentiation.
The first cells may have been anaerobic, heat tolerant, and hydrogen-fed.
Big leaps in our understanding of protein folding can open doors to new protein-based medicines and materials--designed from the ground up.
Scientists have figured out how microbes can suck energy from rocks. Such life-forms might be more widespread than anyone anticipated.
Despite a late start in his field, Kerry Knudsen might know more about lichens than anyone alive today.
Experiments in evolution are exploring what would happen if we rewound the tape of life.
According to a new finding, described as a "shock" by its discoverers, a single mutation 600 million years ago may be responsible for the emergence of complex organisms -- including all of the plants and animals that we are familiar with -- from a single-celled ancestor. This evolutionary accident enabled cells to communicate with each others and therefore to cooperate.
Nature offers a panoply of ways to determine an organism’s sex. How can such a fundamental property be so variable?
