Im discharge to remain a human being, shes going to remain a dog. Thats the way things are going to work. What changes over time are populations of individuals, for very straightforward reasons.
Every species shows variation among individual members of that population. Individuals in a population show what biologists call differential productive success. Some individuals leave more offspring than others. Some people have no children; some people have well-favoured families.
Finally, one of the factors that influences differential reproductive success is how well-suited individuals are to the designate environment in which they find themselvesâ€"how good they are at obtaining food, defending themselves against their enemies, resisting disease, and finding and meeting a member of the opposite word sex and raising offspring. All these things matter.
What Darwin appreciated is that nature herself selects from variants in the population for those that are best able to succeed in this race for differential reproductive success. Over time, and given a steady input of new variation into the population, that muckle change the average characteristics of a species, and it can split one species into two. Those species can go on changing in different directions. Thats what leads to the institution of yet...If you want to get a full essay, order it on our website: Ordercustompaper.com
