Question

Many species _____ display founder effects

Answer 1

you sure the _____ is in the right place?

Answer 2

Probably the best documented example of the founder effect in action is the Galapagos islands.
However the founder effect is seen much more commonly in mountainous regions. Mountains offer many various environmental settings which may cut populations apart. An excellent example of this are populations which cross onto the opposite side of a mountain range than the rest of their species. This is very frequently seen in birds.
