You are correct. I meant 4000 years ago. That would be 2000 BC, wouldn't it?

Just updating the GGG info, not sending a general distribution. Evolution in Your Face by Patrick Huyghe Omni Lake Victoria, Africa's largest lake, is home to more than 300 species of cichlids. These fish, which are popular in aquariums, are deep-bodied and have one nostril, rather than the usual two, on each side of the head. Seismic profiles and cores of the lake taken by a team headed by Thomas C. Johnson of the University of Minnesota, reveal that the lake dried up completely about 12,400 years ago. This means that the rate of speciation of cichlid fishes has been extremely rapid: something on average of one new species every 40 years! 12,400 years ago? Hydrologic cycle came to a screeching whoa for some reason, hmm, what could it have been? To all -- please ping me to other topics which are appropriate for the GGG list.

But climate could be held stagnant if only we would give algore and his global pals access to the National Treasury and central control over the globe's energy use! But no! We, the haters of science and the enviornment, just let the climate change! We are so “stupid.” Now they are going to have to sterilize mankind. See what happens!
