Alligators: A Window Into An Ancient World

How amazing is it that we have creatures as old as dinosaurs living in our midst? Close ancestors of the alligator survived the event that wiped out the dinosaurs about 65 million years ago and as this graphic from the History Channel and Column Five details, there are some fascinating and unusual facts about the large reptile. Thanks to alligators, we have a window into how ancient creatures looked and acted.

Food for thought: while alligator populations are currently large in the southern US, a place where the temperature supports the proper range for hatching eggs, it’s interesting to note how small a change in global temperature would select only one sex of offspring (as sex is determined by temperature during incubation). How much will global warming change the range and the population of alligators in the future?
