It was just February when the taxi startup announced a 'strategic partnership' with the university in order to work on autonomous vehicle technology. But now, at least 40 staff have defected to Uber, leaving Carnegie Mellon in 'crisis'.
The sabertooth tiger may have become extinct due to climate change, lack of large prey and competition from humans. However, thereâs no fossil evidence of tooth wear to suggest sabertooth cats... The sabertooth tiger may have become extinct due to climate change, lack of large prey and competition from humans.
One model guesses that after prey is taken down with a saber-tooth's claws, it rips open the abdomen to cause massive blood loss and death. Perhaps a group of saber-tooths would take down a wooly mammoth (or other megafauna) and then wait for it to bleed out before feeding. Another good hypothesis is that once prey is already held still after being taken down, a solid bite to the throat would quickly take out the windpipe and arteries in many mammals.
