Evolution of seal "Flippers" over time? Seals are aquatic
mammals that evolved from terrestrial mammals with legs. Seals
have appendages that are flipper-like (‘flippers’), which are
adapted for movement in water. Explain how the flippers may have
evolved from legs of a terrestrial ancestor. A) If you were to
go back in time and examine a population of the ancestral
species, would all the individuals look the same? Describe the
variation in the character within the ancestral species that
provided the ‘raw material’ for natural selection to occur. B)
What type (or types) of selection pressure would have favored
the evolution of the character of interest? C) How would the
character of interest allow the organism that had it to
reproduce more than an organism that lacked it? Re: Evolution of
