This was the original population of jelly beans.
This population split into 2 populations

| This is one of the new populations. Notice that a new jelly bean appeared (purple) as if it were a mutation. Notice as well that the yellows have died off. | This is the other new population. Notice that a new jelly bean appeared (green) as if it were a mutation. Notice as well that the maroons have died off. |
These two jelly bean gene pools represent speciation. Starting as a common gene pool, a separation occurs into two, isolated gene pools. Whatever changes occur in one jelly bean gene pool (adding purple, removing yellow for instance) has no effect on the other jelly bean gene pool. Likewise different changes occurred in the other gene pool separate from the first. In nature, these changes can occur because of different natural selection pressures and mutations. After time has passed, you have two distinct gene pools. In nature these gene pools could have changed enough to be two different species.
