There is no central force, except that anything which does not hinder a gene's chance of reproducing will allow whatever species that gene belongs to live on.
If a trait helps a species to survive, that trait will be "selected".
Look at it this way, if a particular trait means that some members of a species is less likely to breed than other members, that trait will die out eventually. This could mean that lions which have shorter claws than their fellows, or cheetahs which can't run as fast as their fellows will go hungry, and be less successful in having and rearing cubs which carry their genes.
That is not so much a force driving evolution as a force culling those members of a species which are "less fit" for survival than their fellows
Reproductive variation is central to evolution. All else in evolutionary theory follows directly or indirectly from the fact that organisms reproduce with variation.
To Darwin, the central concept of organic evolution was natural selection. He proposed that individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to their offspring, leading to changes in the characteristics of a population over time.
A force between two particles that is not directed along the line connecting them; for example, a tensor force between two nucleons. anything that is not central force is a non central force. study about central forces to understand this better.
