Abiogenesis



The Theory of Evolution provides a rich explanation for why we see the diversity of life here on Earth. There are so many lines of evidence, from genetic drift to the fossil record. But how did life start? How did things go from a collection of raw materials to the building blocks of life, giving evolution and natural selection a way to take over? That first step, from non-life to life is called "abiogenesis", and it's one of the most important questions science can answer.

The Day We Learned To Think

Understanding of humans' earliest past often comes from studying fossils. They tell us much of what we know about the people who lived before us. There is one thing fossils cannot tell us; at what point did we stop living day-to-day and start to think symbolically, to represent ideas about our environment and how we could change it? At a dig in South Africa the discovery of a small piece of ochre pigment, 70,000 years old, has raised some very interesting questions.

Origins Of Us Episode 1 Bones

Broadcast (2011) Dr Alice Roberts reveals how your body tells the story of human evolution. The way you look, think and behave is a product of a 6 million year struggle for survival. We have uncovered the secrets of the atom and travelled to the moon. But how did humans come to be so successful?



This series explores the anatomical changes that have given us, and our ancestors, the edge. Everything from the way that we walk, to the shape of our jaw and even the way our thumbs move connects us intimately to the struggles and triumphs of our ancestors. Yet many of those changes have come at a surprising cost and the problems we face now are a direct consequence of our evolutionary journey. As much about our bodies today as about our bodies 6 million years ago, Origins of Us will change the way you see yourself.

Elaine Morgan on human evolution in watery habitats

Elaine Morgan is a tenacious proponent of the aquatic ape hypothesis: the idea that humans evolved from primate ancestors who dwelt in watery habitats.



Hear her spirited defense of the idea -- and her theory on why mainstream science doesn't take it seriously.
