That would be Charles Darwin.
Isolation such as geological can cause speciation because if one species where divided into two because of geological reasons, they're likely to change their behaviors and physical appearances to match that region.

Answer:
The two blue budgies are most likely to be yyBb each
Explanation:
there are 3 different scenarios possible for crossing blue budgies:
1) yyBB crossed with yyBB
this is not possible because it does not allow for the genotype yybb (white budgies)
2) yyBB crossed with yyBb
again, this cross will not yield the genotype yybb required for white budgies as given in the problem statement
3) yyBb crossed with yyBb
which leaves us with this option being most likely the genotype of the parent budgies who will have white budgies as offspring
Hope that answers the question, have a great day!
