Sentences with phrase «echolocation evolved»

The study showed that microbats fall into two separate categories, reaffirming that throat - derived echolocation evolved twice, the researchers report in the 22 January early edition of Proceedings of the National Academy of Sciences.

Microbats, the group of bats that emit echolocation signals from the larynx, came under close scrutiny because, surprisingly, some molecular studies divided them into two groups that diverged long ago, suggesting that echolocation evolved twice.

New fossil suggests echolocation evolved early in whales.

«It means that high - frequency hearing fundamental to echolocation evolved through the same molecular route,» says Stephen Rossiter of Queen Mary, University of London.

Not exact matches

Some species of dolphins and whales adapted to the new environment by evolving echolocation, which allows them to «see» with their ears.

Echolocation is a skill that has evolved independently several times in the animal kingdom in response to low visibility conditions — whether at night, as with bats and a few nocturnal birds, or in murky water, as with whales and dolphins, Wiegrebe notes.

Hyopsodus was a weasel - like ungulate that lived 55 million years ago, around the time that bats evolved echolocation.

Frog - eating bats pinpoint their prey by their calls, and have evolved unique hearing that allows them to detect both the high - pitched squeaks of their echolocation system and the low - frequency sound of calling frogs.

Lead author Simon Whiteley from the Centre for Ultrasonic Engineering at the University of Strathclyde, said, «We aim to understand the echolocation process that bats have evolved over millennia, and employ similar signals and techniques in engineering systems.
