But could a second, larger impact off the coast of India share the blame? The Left-Handed Lobster http://www.astrobio.net/news/article1280.html Nature versus nurture, what is the cause of the lop-sided claw weight in lobsters?

Thousands of 600 million years old embryo microfossils have been found in China that may be among the first animals. It is a case of preserving the seemingly unpreserveable. Dark Echoes from Titan http://www.astrobio.net/news/article1278.html Looking at radar reflections of Titan, scientists are puzzled by what they see: is the surface dotted with black pools or two different materials, one light, the other dark?
