Humans evolved in Africa, along with chimpanzees, gorillas and monkeys. But primates themselves appear to have evolved elsewhere—likely in Asia—before colonizing Africa. At the time, around 50 million years ago, Africa was an island isolated from the rest of the world by ocean—so how did primates get there?

Since the mid-20th century, scientists have been looking for evidence of intelligent life beyond our solar system. For much of that time, scientists who are engaged in the search for extraterrestrial intelligence (SETI) have relied on radio astronomy surveys to search for signs of technological activity (aka "technosignatures"). With 4,375 exoplanets confirmed (and counting!) even greater efforts are expected to happen in the near future.

Scientists from Stony Brook University and the Max Planck Institute of Animal Behavior have pieced together a timeline of how brain and body size evolved in mammals over the last 150 million years. The findings, published in Science Advances, show that brain size relative to body size—long considered an indicator of animal intelligence—has not followed a stable scale over evolutionary time.

What makes the human brain special? It's not the time it takes to mature, according to new research. Scientists report the human frontal cortex, the part of the brain involved in higher-level thinking and reasoning, follows a developmental trajectory similar to that of other primates including chimpanzees and macaques.

Fruits and veggies are good for you and if you are a lemur, they may even help mitigate the effects of habitat loss.
