Research into the sense of touch in worms wins Eppendorf/Science Prize
...own as Caenorhabditis elegans, the entire cellular anatomy of its nervous system is known. Scientists hope to apply their knowledge about the nematode's sense of touch to larger and more complex animals.

"There were 2.5 million to 3 million years of bipedal walking [by australopithecines] without ever looking like a human, so is walking going to be what suddenly transforms the hominid body?" he asks.

...sm," said Ulrike Heberlein, PhD, UCSF professor of anatomy and senior author on the paper. "Insulin is already known to act in the nervous system to regulate food intake, so it makes sense that it would influence the response to other substances the body senses as rewards, such as alcohol or drugs of abuse."...Model simulates dynamics of heart rhythm disorders

As modern human anatomy is documented at earlier and earlier sites, it becomes evident that there was a great time gap between the appearance of the modern skeleton and 'modern behavior.'"
