Two common species of frogs from the genus bombina (b. bombina and b. variegata) live in similar latitudes and ecological conditions, but in two different regions, central and eastern europe. in a narrow strip between these regions, scientists observed a third species, which might have been a hybrid between the former diverging populations of the ancestral species. what evolutionary process might be responsible for the speciation in bombina? top of form
a. allopatric speciation
b. parapatric speciation
c. sympatric speciation
d. none of the above
e. bottom of form
