Scientists have uncovered another secret bats

February 17 2008

The study found the most ancient remains of the moment of bats found in the U.S. state of Wyoming, has led scientists to answer the question: which came first with these unusual animals: the ability to fly or echolocation?

In revealing this secret specialists helped the study of the skeleton of a bat Onychonycteris finneyi, whose age is estimated at 52 million years. A detailed study of the skull and wings showed that these bats first learned to fly, and only later developed the ability to echolocation - orientation in space using ultrasound.

The mouse, once lived in the tropics or subtropics and eat insects, did not know how to use echolocation - a comparative analysis of the skull showed the ancient remains of mice and later, the bats found in the archaeological zone of Messel in Germany. In this case, the bats from Messel pit lived "only" 5 million years later, but already used echolocation. The work of scientists is published in the prestigious scientific journal Nature.
