Fire produces toxicants that can pose a health risk. Our ancestors had the ability to detoxify them, but harmful mutations have hampered our capacity for it
Human technology is advanced thanks to our socialising. By staying mobile and/or living in large groups we can learn from more people.
Creationists claim to have done research showing eoliths are ancient artefacts that turn evolution on its head. In reality, their work is hopelessly flawed.
Cooking could have given us the energy to evolve big brains. But the difference between the invention of fire and our brains growth reveals this is false
Over the course of human brain evolution our noggin has become more bloodthirsty. Literally. It needs more blood than would be expected given its size.
A long-term study of the “palaeolithic diet” of Australopithecus reveals they were extremely flexible, well suited to the climate change they experienced.
Research has found that a high status increases men’s reproductive success. Thus, the drive to increase status likely evolved to maximise this success
Only ~10% of Homo sapiens are left-handed. This is true in both modern populations and fossils. The dominant hand of more than 50 European fossils has been identified. 47 are right-handed (92%). This stands in stark contrast to our chimpanzee cousins; for whom hand preference is closer
People have evolved to flourish in social groups. As a result of this social isolation is bad for us, increasing some health risk factors more than smoking
Glaciers covered much of Europe around 20,000 years ago. But that was their peak, called the Last Glacial Maximum. After that, they began retreating and Europe began warming. Humans exploited this change, spreading north into places previously covered by ice. It seemed that things were
