The armour of the 380 million year old placoderm fish
Scientists have long believed that our distant cousins are the placoderms, and ancient group of armoured fish. But a new study is casting doubt on that view.
Bonobo Jasongo at Leipzig Zoo has a hunch about what you’re thinking.
Realizing that others' minds hold different thoughts, feelings and knowledge than your own was thought to be something only people could do. But evidence is accumulating that apes, too, have 'theory of mind.'

Human sacrifice seems horrifying and costly. But there might be a reason so many early human societies practiced it.
How has a retrovirus survived intact within the human genome for millennia, and how has it affected us?

New excavations at an Indonesian cave have pushed back the time the 'hobbits' disappeared to about 50,000 years ago.
Standing up for what’s right can come with a cost to the individual – but also a benefit.
It helps society function when people punish selfish acts, even at a personal cost. A new theory suggests third-party punishment also confers some benefits on the punisher.
With moralistic gods watching, it’s easier to be fair and cooperative.
For human groups to grow from small, intimate communities to the huge interconnected societies we know now, people needed to be willing to cooperate with strangers. Religion might have played a big role.
A panoramic view of the interior of the Blombos Cave, which holds fascinating insights into human evolution.
The discovery of the world's oldest jewellery at the Blombos Cave in South Africa has resulted in a paradigm shift in our understanding of human evolution.

A new study is rewriting our understanding of archaic humans and how they may have interacted with early humans.
Author and ecologist Paul Ehrlich, speaking on Q&A.
Author and ecologist Paul Ehrlich told Q&A that humans, on average, have associated with only about 150 other people for millions of years. Is that right?
Hands down amazing: nearly 2 million year-old pinkie bone.
The discovery of the oldest modern human-like pinkie bone suggests that hands emerged very early in human evolution.
Human eyes are unique among primates for their range of iris colours and unpigmented sclera.
The science about our special senses - vision, smell, hearing and taste - offers fascinating and unique perspectives on our evolution. Yet it remains patchy; we know surprisingly little for example about…
Neanderthals were just too macho for culture.
Ditching the testosterone meant humans were able to develop cooperative culture.
The evolutionary tree may not be this simple.
The challenge we face after a century of extraordinary discoveries is pinning down the lineage and mapping the evolutionary route through which we as human beings got here.
Chimpanzees are wily enough to adapt in some ways when people encroach on their turf.
Apes and people are sharing habitat more than ever. As apes are pushed into novel situations, we can see how they adapt and maybe find clues into early human evolution.
The move to cultivating the land for food has dramatic impact on the male population.
The change of lifestyle from 10,000 years ago had a dramatic impact on the male divefrsity revealed in DNA.
Tsimane hunter with prey after a successful hunt. How are his hormones responding?
Levels of a male sex hormone known to influence aggression and a "love" hormone that promotes bonding both rise in traditional hunters headed home after the kill. What's going on?
