Discoveries in a Lake
Scientists have discovered a lake in southwest Florida/ that is thousands of years old./ Discoveries made there have lead scientists to believe/this is one of the most important areas for studies/of ancient man, animals and climate in North America. /
At the bottom of the lake,/they have found a great quantity of human remains/and plant and animal fossils. / This gives the scientists a rare chance/to study combinations of climate and ecology/that prepared the way for human survival in America./
The lake is at least 240 feet deep at one point. / It is rich in minerals and contains very little oxygen. / This has helped to preserve specimens in the lake/that would usually have been destroyed. / Because several types of animals were found that are now extinct,/it raised sever- al questions among scientists./Did these animals die of natural causes,/or were they hunted into extinction by human beings?
