Sort
Which mode of speciation is it?
Tap a card, then tap its group.
Ask where the two groups live while they diverge.
Assumptions
•
Allopatric speciation: a barrier or distance splits the range, and the parts diverge in isolation.
•
Sympatric speciation: a new species arises inside the parent’s range, with no barrier in space.
•
Parapatric speciation: neighbors along an edge or a gradient diverge although some genes still flow.
