Research at CCMB in Hyderabad reveals genetic links between diet quality and brain size evolution in primates.

Human testicles are much smaller, in proportion, to some of our primate cousins. Evolution can tell us why. But the size of ...

The human body is a machine whose many parts—from the microscopic details of our cells to our limbs, eyes, liver and brain—have been assembled in fits and starts over the 4 billion years of our ...

The discovery may explain why cutting edge CAR T-cell therapy has managed to revolutionized treatment for blood cancer but ...

When the top spotty fish in a tank disappears, the runner-up turns aggressive within minutes, rushing and nipping rivals ...

Recent discoveries using lab-grown brain organoids, or "mini-brains," suggest that testosterone increases brain size while estrogens improve connectivity between neurons. Humans, unlike most other ...

Size matters when it comes to evolution But convergent evolution becomes something useful when we think of it as a kind of natural experiment. The size of primate testicles gives us a classic example.
