Study Finds 2 Extinct Frog Species 'Existing' in One Body

When speaking about chromosomal count, it is but an unusual event to have one species bearing more than once set of chromosomes. But through time and due to the development and diversion and converging of species, there are cases that chromosomal count may go beyond the normal. What's more interesting is that a new study found out about the "existence" of two extinct frog species' chromosomes found to be the structural make-up of one frog species--the African clawed frog!
