It is a pecotonic way of origin if drastic cellisis more going to active meosis phase.
4 cells that have only 23 chromosomes, because they are sex cells.
Differential evolution is when a putati creates a sort of egg that needs to be fertilized therefore creating butt sex between the duck and goose. However Swarm optimization can be a number of things e.g - A cake - A lubricant penis Any of the sort. Hope this helped !
