It was hotter back then

Once upon a time, Ice Age creatures like the mammoth had a hard time finding water in the area now known as the Everglades.

But that was more 100 centuries ago, shortly after the last Ice Age -- a mostly dry and very hot period, said archaeologist Willard Steele, who heads the Tribal Historic Preservation Office at the Ah-Tah-Thi-Ki Museum in the Seminole Tribe's Big Cypress Reservation south of Clewiston.

Richard C. Hulbert, vertebrate paleontologist at the Florida Museum of Natural History in Gainesville, said fossil discoveries help piece together the puzzle of how Ice Age mammals lived and became extinct in South Florida.

''The area was hotter than it is today, with periods of drought,'' said Hulbert, who elaborated on the theory that Florida's then dry, hot weather, along with aggressive hunting by humans, critically upset the food chain.

What caused that warming? Ask the Goracle. He would know.

It was all that hunting by humans.

Oh what a great earth it would be if it wasn't for all those pesky humans.
