Question

is over production also a factor that could lead to speciation ?

Answer 1

Here is your answer

ya sometimes it could lead but no

Four factors which lead to speciation are :

1) Gene flow between the populations of one species is restricted to allow them to diverge.

2) A component of the divergence products a complete barrier to inter-breeding called a mating isolation mechanism.

3) The initial barrier can be either spatial or temporal.
