Cheaters have been around since the Age of Amoeba

UPDATE: This is generating some good discussion, which is what I wanted to help me explain why this is relevant. It’s a study about amoeba, but reveals something I think about biological “laws” of all cooperative societies and genetics. It’s very relevant to the nature-nurture debate, and to national politics and policies. UPDATE #2: The cheating referred to in this post is defined as “social cheating” meaning to take some advantage over and above contributions to the social group. The amoeba are a simple “model system” that may help us learn more about the factors that influence the balance of “cheaters” versus “cooperators” in any social species.

See the critics and my replies at #7 and #16. Give it your best shot. :- )  Jo

You might think that corruption in science has only been around for 20 or 30 years. But I say this problem has been around since the Age of Amoeba.

The day after cells evolved to cooperate, some of them learnt to cheat. The battle of the cooperators versus the cheaters hasn’t stopped since and humans are the most socially evolved cooperators on the planet, (which just means we have more socially [...]

Two million years of climate change made us what we are

Two million years of climate change has made us human — in a ying meets yang contradiction, while climate change destroyed cultures and groups,  without it, we would not be who we are. The brutal forces of Nature tested our ancestors with droughts, storms, floods and tidal surges, but if the climate had stayed the same, would we have had Bach, Leonardo, and Newton?

At the end of the day, we have a civilization that allows millions of people to pursue happiness without fear that they will die of dysentery, be murdered by marauding barbarians, or lose their children to slave traders.

We are the lucky bastards at the end of a long line of poor sods who struggled and suffered to stay one step ahead of the reaper.

Here are two stories of studies that suggest dramatic effects of climate change on long lost peoples. The second, below, may finally explain the disappearance of the mysterious well developed aboriginal artform known as the “Bradshaw” style.
