Not exact matches
The longer - lived animals are also the smarter ones, or the bigger ones, or the ones like birds and
bats that
evolved adaptations such as
wings to make their lives safer.
For example, insects,
bats and birds have all
evolved wings that are similar in function but have completely different origins, eyes have emerged multiple times, and there is good evidence that nervous systems have also
evolved several times, with some creatures possessing strange systems unlike the brains and spinal cords we are used to.
Birds and
bats both fly, but they
evolved their
wings separately.
