Subject: Oldest Human Ancestor pieced together
Something that might be of interest:



http://news.nationalgeographic.com/news/2009/10/091001-oldest-human-skeleton-ardi-missing-link-chimps-ardipithecus-ramidus.html

Scientists today announced the discovery of the oldest fossil skeleton of a human ancestor. The find reveals that our forebears underwent a previously unknown stage of evolution more than a million years before Lucy, the iconic early human ancestor specimen that walked the Earth 3.2 million years ago.


Although the 'sex for food' hypothesis for the origin of bipedality at the bottom struck me as particularly ridiculous.

Why? It is intriguing.

Wear patterns and isotopes in the hominid teeth suggest a diet that included fruits, nuts, and other forest foods.


Herbivores? What these other jungle foods might have been?sticking out tongue



If White and his team are right that Ardi walked upright as well as climbed trees, the environmental evidence would seem to strike the death knell for the "savanna hypothesis"—a long-standing notion that our ancestors first stood up in response to their move onto an open grassland environment.






Lovejoy sees these changes as part of an epochal shift in social behavior: Instead of fighting for access to females, a male Ardipithecus would supply a "targeted female" and her offspring with gathered foods and gain her sexual loyalty in return.
To keep up his end of the deal, a male needed to have his hands free to carry home the food. Bipedalism may have been a poor way for Ardipithecus to get around, but through its contribution to the "sex for food" contract, it would have been an excellent way to bear more offspring. And in evolution, of course, more offspring is the name of the game (more: "Did Early Humans Start Walking for Sex?").



Is it absurd? Why ?

Lucy,Ardi,hulalulaloooo!laughing



Thank you.

Because it's pure speculation without a shred of evidence, nor is any evidence even possible.

All conjectures in this area are nothing more than fictional narratives strung together by writers with fanciful imaginations.

I mean, look at the complexity of the 'explanation' provided. There is no way that there could be any evidence to support--or falsify--this story.

The food for sex hypothesis does seem far-fetched to me.

I'd love to read the arguments of the one who proposed it.

Great subject for a parody. They find scraps of bone embedded in rock. Takes them forever to tease it all out. They assemble a skeleton made up of the remains of various individuals. All the scraps are millions of years old. Am I getting it right?

"Hm. She is small and kinda neat looking. She must have been quite the babe..." laughinglaughing

Your particular rejection of particular conjecture,as opposed to other ones warrants some strong assertions,reasons on your behalf,in support of that particular theory.
