Sexual selection could be a vector of reproductive isolation ( which can lead to speciation) but there are lots of other


reproductive isolation occure when a species divide in two branch and due to different factors, members from a branch can't reproduce with the members of the other.

a geographical isolation ( ex: separation of the pangia) separated individual of the same species that evolved separately.

For instance, if the change among the two branche get to change the phenologie of the reproduction ( time when they reproduce) there will be a temporal reproductive isolation ect ...
further more if the two branchs change in a way that make individuals from a branch unappealing for members of the other branch it will be a reproductive isolation by sexual selection.
