Subject: Professor Alice Roberts - Origins of Us: Human Anatomy and Evolution




Friday 10 February 2012, 4-5pm

Alice Roberts, Professor of Public Engagement in Science at the University of Birmingham presents a lecture in association with the Great Read At Birmingham (GRAB) project.

Clinical anatomist, author and broadcaster Alice Roberts gave her lecture as part of the Darwin Day celebrations, with a focus on the anatomy and evolution of humans as a species.

'We are all members of a very special species. Whilst our anatomy and physiology is undoubtedly that of an ape, we have done things that no other ape can do, and become the most successful ape on the planet. Today, our global population numbers almost
seven billion; we survive and thrive everywhere from the tropics to the Arctic.

So just what is it that makes us so special? In some ways we are so similar to our closest cousins, chimpanzees, but it's also clear that we are a world apart. But we can understand ourselves, how we got to where we are today, by going back into our deep past,
to the time when we were just another African ape. And then tracing the small changes that over time, and unpredictably, led to us becoming human.

The answers to the question of 'what makes us human?' lie buried in the ground in the form of fossils and traces of our ancestors, but also lie deep within the form and function of our bodies.'

Subject: Re: Human impact on nature 'dates back millions of years'

The impact of humans on nature has been far greater and longer-lasting
than we could ever imagine, according to scientists.

Early human ancestors living millions of years ago may have triggered
extinctions, even before our species evolved, a study suggests.

A decline in large mammals seen in Eastern Africa may have been due to
early humans, researchers propose.

Extinction rates started to increase from around four million years ago.

This coincides with the period when ancient human populations were
living in the area, as judged by fossil evidence.

"We are now negatively impacting the world and the species that live in it
more than ever before. But this does not mean that we used to live in
true harmony with nature in the past," said study researcher, Dr Søren
Faurby of the University of Gothenburg.

"We are extremely successful in monopolising resources today, and our
results show that this may have also been the case with our ancestors."

The researchers looked at extinction rates of large and small carnivores
and how this correlated with environmental changes such as rainfall and
temperature.

They also looked at changes in the brain size of human ancestors such
as Australopithecus and Ardipithecus.

They found that extinction rates in large carnivores correlated with
increased brain size of human ancestors and with vegetation changes,
but not with precipitation or temperature changes.

They found the best explanation for carnivore extinction in East Africa
was that these animals were in direct competition for food with our
ancestors.

They think human ancestors may have stolen freshly-killed prey from the
likes of sabre-toothed cats, depriving them of food.

"Our results suggest that substantial anthropogenic influence on
biodiversity started millions of years earlier than currently assumed," the
researchers reported in the journal Ecology Letters.

Co-researcher Alexandre Antonelli of the Royal Botanic Gardens, Kew,
said the view that our ancestors had little impact on the animals around
them is incorrect, as "the impact of our lineage on nature has been far
greater and longer-lasting than we ever could ever imagine".

A landmark report last year warned that as many as one million species
of animals and plants are threatened with extinction in the coming
decades.

A more recent study found that the growth of cities, the clearing of
forests for farming and the soaring demand for fish had significantly
altered nearly three-quarters of the land and more than two-thirds of the
oceans.

URL: Study: Last Common Ancestor of Humans and Apes Looked Like Gorilla or Chimpanzee


why so?

Ever since we evolved, began hunting and killing & eating critters, used
fire, changed landscapes for farming, mined and smelt metals, we have
have not lived in 'true' harmony - quite the opposite.

Maybe around million years ago just as we split from a common ape
ancestor we did 'no harm' - but since then - look around you....

.............

Humans split from our closest African ape relatives in the genus Pan
around six to seven million years ago. We have features that clearly link
us with African apes, but we also have features that appear more
primitive. This combination calls into question whether the Homo-Pan
last common ancestor looked more like modern day chimpanzees and
gorillas or an ancient ape unlike any living group. A new study, published
online in the Proceedings of the National Academy of Sciences, suggests
that the simplest explanation – that the ancestor looked a lot like a
chimpanzee or gorilla – is the right one, at least in the shoulder.

you forget that the apes and other primates descended from humans and their disgusting activities, not the other way around...

??

Are you refering to interbreeding between hominids - or is that a lteral
claim. If the latter any links to evidence of your extraordinary claim.

Our evolutionary path is bit like Assange's unrestrained urges, I agree
quite murky and opportunistic, but then marriage is a relatively recent
concept ;-)

men and a female animal cannot produce offspring...but a woman and a male animal can..and that's how and why we have the other primates...check the dna if you have doubts...

URL: Multiple lines of mysterious ancient humans interbred with us


So let's get this straight - you're claiming in the past (8 million years ago or
so?) female homo sapiens interbred with lowly ape male creature giving rise
to chimpanzees, gorillas and orang-utans?

If so that'll rewrite the textbooks...
