65 million years ago, dinosaurs experienced bad weather and an asteroid impact, but scientists say their real problem was too many males for the number of females. They think that the sex of dinosaurs, like crocodiles today, depended on the temperature the day they were born. Debris from the asteroid impact blocked the sun and cooled down the climate, leading to the birth of too many males.
In bbcnews.com,David Whitehouse quotes infertility expert Sherman Silber as saying, "The Earth did not become so toxic that life died out 65 million years ago; the temperature just changed, and these great beasts had not evolved a genetic mechanism (like our Y chromosome) to cope with that." But crocodiles and turtles had already evolved at the time of the dinosaur extinction, so why didn't they go extinct as well? "These animals live at the intersection of aquatic and terrestrial environments, in estuarine waters and river beds, which might have afforded some protection against the more extreme effects of environmental change, hence giving them more time to adapt."
Rhinos seem to have the same sort of problem today, as a group of visitors to a British safari park discovered when one of them tried to have sex with their car. When tourist Dave Alsop stopped his car to take pictures of two-ton white rhinoceros Sharka mating with his girlfriend Trixie at the West Midland Safari Park, the rhino left Trixie and tried to mount Alsop's Renault instead, denting the doors and ripping off the side mirrors. When Dave drove away, Shaka chased the car in hot pursuit. "He was a big boy and obviously aroused," Alsop says. "He sidled up against us. The next thing I know he's banging away at the car and it's rocking like hell."
Gregg Braden says there's coded information that has been found deep within the DNA of our bodies. What is so extraordinary about this is that it can be read as a message in a number of ancient biblical alphabets.
