Primate Theory
Some scientists have proposed that flying foxes are descended from primates rather than bats and that mammalian flight ability has evolved more than once. This theory is not accepted by most modern zoologists. For more details see: Flying primates theory.

Famous quotes containing the word theory:
“A theory of the middle class: that it is not to be determined by its financial situation but rather by its relation to government. That is, one could shade down from an actual ruling or governing class to a class hopelessly out of relation to government, thinking of gov’t as beyond its control, of itself as wholly controlled by gov’t. Somewhere in between and in gradations is the group that has the sense that gov’t exists for it, and shapes its consciousness accordingly.”
—Lionel Trilling (1905–1975)
