A situation which is most likely to be a driving force for changes in a species is increased mating events due to environmentalstability.
<h3>What is a species?</h3>
A species can be defined as a biological classification of related organisms that have similar characteristics and they are capable of mating (breeding) with one another in a cycle or different seasons.
This ultimately implies that, increased mating events between living organisms due to environmentalstability is a situation which is most likely to be a driving force for changes in a species.
