Scientists and biologists are literally racing against the clock to discover new frontiers relating to increasing the life span of man. These exciting discoveries will in turn benefit the animal kingdom. In the early 20th century, German-born biologist Jacques Loeb performed an experiment that resulted in proving the life span of the fruit fly could be halved by every ten-degree increase in temperature.

Biologists and Scientists continue to seek ways to extend man's life span. In turn, those discoveries will benefit our animal kingdom.

However, if you look at the life of a Galapagos tortoise you'll find an already really impressive life span. But what about other animals? What are their maximum life spans? Let's take a fascinating look into the Window of Nature.
