For most of our evolutionary history—for most of the time anatomically modern humans have been on Earth—we've shared the planet with other species of humans. It's only been in the last 30,000 years, the mere blink of ...

Scroungers and parasites seem to show up in nature wherever life produces something useful, and that includes parental care. Among birds, for example, the practice of laying eggs in other birds' nests is surprisingly common.

The immune system fends off pathogens in a wide variety of ways. For example, the immune system's memory is able to distinguish a foreign protein it has encountered before and to react with a corresponding antibody. Researchers ...

Highly developed seed plants evolved deep root systems that are able to sense Earth's gravity. The how and when of this evolutionary step has, until now, remained unknown. Plant biologists at the Institute of Science and ...
