So how and why did humans evolve to become expert throwers? In two papers in The Quarterly Review of Biology, we explored the ecological causes and evolutionary consequences of throwing in humans. Sticks and stones that break bones Humans are the only species that can throw well enough to...

—What did the last common ancestor between humans and apes look like? "It may be a sort of unintended consequence that TBXT deficiency gives you a short tail … but it makes it more likely that you don't get that complete neural closure," meaning a hole is left in the neural tube, ...
“In short, the human ability to run long distances, such as a marathon, is neither a simple byproduct of the ability to walk bipedally, nor a biologically aberrant behaviour. Instead, running has deep evolutionary roots. Although humans no longer need to run, the capacity and proclivity to...
Extant scientific consensus is that humans first evolved during a period of rapid climate fluctuation between wet and dry, and that most of the adaptations that distinguish humans from the great apes are adaptations to a terrestrial, as opposed to an earlier, arboreal environment. Few pale...
Did losing our fur allow us to read each other's emotional responses such as fuming or blushing? Scientists aren't exactly sure, but biologists are beginning to understand the physical mechanism that makes humans the naked apes. In particular, a recent study in the journalCell Reportshas begun...
We live in an age when all manner of scientific knowledge—from climate change to vaccinations—faces furious opposition. Some even have doubts about the moon landing.
How did Homo sapiens become the only hominid species? What characteristics do humans share with all primates? What makes a gibbon an ape? Why are great apes endangered? How do the skulls of adult chimpanzees and humans differ? How do non-human primates see compared to humans? Why are fur ...
How did humans evolve? Pixabay How did humans evolve? Humans emerged in Africa about 6 million years ago, evolving from a common ancestor of humans and apes. Over the course of the past several million years, there have been about 15–20 different early human species, and last April, scien...
Why would humans evolve with this variation? Evolutionarily, having a mixture of morning people and night owls allows a population to reduce its vulnerability in nighttime to a shorter period of time. Example: As morning people sleep earlier (say at 10PM), night owls can keep up the watch....
