allochronic speciation (s) (noun), allochronic speciations (pl)
A form of organic evolution starting from a life-giving reproduction that happens due to a change in time of breeding which lessens or stops gene flow between two groups of a species: Allochronic speciation is the process of developing different biological groups as a result of members of the population that have different breeding seasons or patterns, or differing in the use of time during the day or night, rather than through geographic separation.
