While on a trip through Africa and South America, you notice that the current (as well as fossilized) animals of western Africa and Brazil show highly similar morphologies (body plans). Given your background in General Biology, you suggest that this is MOST likely because of:a) convergent evolution owing to similar evolutionary pressures
b) the climates of Brazil and western Africa are highly similar
c) animals from Africa moved to Brazil during the "Great American Interchange"
d) South America and western Africa were once part of the same land mass
e) the large sizes of Africa and South America have provided many different habitats in which plants and animals could evolve
