Human Evolution Grinds to a Halt
YAHOO! (UK & IRELAND): Human evolution is grinding to a halt, according to a leading genetics expert.

The gloomy message from Professor Steve Jones is: this is as good as it gets.

Prof Jones, from the Department of Genetics, Evolution and Environment at University College London, believes the mechanisms of evolution are winding down in the human race.

At least in the developed world, humans are now as close to utopia as they are ever likely to be, he argues. Speaking at a UCL Lunch Hour Lecture in London, Prof Jones said there were three components to evolution - natural selection, mutation and random change.

He said: "In ancient times half our children would have died by the age of twenty. Now, in the Western world, 98% of them are surviving to the age of 21. Our life expectancy is now so good that eliminating all accidents and infectious diseases would only raise it by a further two years. Natural selection no longer has death as a handy tool."

Mutation rate was also slowing down, he said. Although chemicals and radioactive pollution could cause genetic changes, one of the most important mutation triggers was advanced age in men. "Perhaps surprisingly, the age of reproduction has gone down - the mean age of male reproduction means that most conceive no children after the age of 35," said Prof Jones. "Fewer older fathers means that if anything, mutation is going down."

Random alterations to the human genetic blueprint were also less likely in a world that had become an ethnic melting pot, according to Prof Jones. Human Evolution Coming to a Halt >>> Press Association | October 7, 2008

Charles Darwin’s Works Go Online

BBC: The first draft of a book which changed the world's attitude to evolution is available for the first time online.

Papers which led to Charles Darwin's theory of evolution were previously only available to scholars at Cambridge University's library.

The draft notes are among 20,000 archive items created by the 19th Century naturalist during his lifetime.

Dr John van Wyhe, a Darwin specialist at Cambridge University, said: "He changed our understanding of nature."

World-changing ideas

The online archive about Charles Darwin is so vast it would take someone two months to view it all if they downloaded one image per minute.

"His papers reveal how immensely detailed his researches were. The family has always wanted Darwin's papers and manuscripts to be available to anyone who wants to read them," said Dr van Wyhe.

"The fact that everyone around the world can now see them on the web is simply fantastic.

"Charles Darwin is one of the most influential scientists in history. The collection of his papers now online is extremely important and therefore very exciting.

"This release makes his private papers, mountains of notes, experiments and research behind his world-changing publications available to the world for free." [Source: Darwin’s First Draft Goes Online]

Homo Erectus Appeared 400,000 years Earlier, Says German Archaeologist

TIMESONLINE: Our earliest ancestors gave up hunter-gathering and took to a settled life up to 400,000 years earlier than previously thought, according to controversial research.

The accepted timescale of Man’s evolution is being challenged by a German archaeologist who claims to have found evidence that Homo erectus — mankind’s early ancestor, who migrated from Africa to Asia and Europe — began living in settled communities long before the accepted time of 10,000 years ago.

The point at which settlement actually took place is the first critical stage in humanity’s cultural development. Rise of man theory ‘out by 400,000 years’ (more) By Dalya Alberge
