Dr Alice Roberts asks one of the great questions about our species: are we still evolving? There’s no doubt that we’re a product of millions of years of evolution. But thanks to modern technology and medicine, did we escape Darwin’s law of the survival of the fittest?

Alice follows a trail of clues from ancient human bones, to studies of remarkable people living in the most inhospitable parts of the planet, to the frontiers of genetic research to discover if we are still evolving – and where we might be heading.

In a Horizon special, naturalist Sir David Attenborough investigates whether the world is heading for a population crisis. In his lengthy career, Sir David has watched the human population more than double from 2.5 billion in 1950 to nearly seven billion. He reflects on the profound effects of this rapid growth, both on humans and the environment.

While much of the projected growth in human population is likely to come from the developing world, it is the lifestyle enjoyed by many in the West that has the most impact on the planet. Some experts claim that in the UK consumers use as much as two and a half times their fair share of Earth’s resources.

Marcus meets some remarkable individuals – Tommy, an obsessive artist who uses his whole house as his canvas; Derek: blind, autistic, and a pianist with apparently prodigious gifts; Claire who is also blind, but whose brain has learnt to see using sound.

Science Under Attack

9 months ago
Watch Free Online Science Documentaries

Nobel Prize winner Sir Paul Nurse examines why science appears to be under attack, and why public trust in key scientific theories has been eroded – from the theory that man-made climate change is warming our planet, to the safety of GM food, or that HIV causes AIDS.

He interviews scientists and campaigners from both sides of the climate change debate, and travels to New York to meet Tony, who has HIV but doesn’t believe that that the virus is responsible for AIDS.

This is a passionate defence of the importance of scientific evidence and the power of experiment, and a look at what scientists themselves need to do to earn trust in controversial areas of science in the 21st century.
