According to the theory of natural selection, by Darwin, species transform within time
through alteration of species. According to Darwin, there are three essential and appropriate
circumstances for the process of natural selection:
c. Differential reproduction centered on variation.
Individuals of the definite species exhibit a number of differences, thus causing the fittest
individuals capable of surviving since their DNA will be replicated by their progenies. The fact
that various individual species possess dissimilar DNA leads to the probability of one individual
having superior genes that allow them to endure hunting by predators. Dissimilar DNA also
makes it possible for these individuals to transfer similar mutations and genes to their offspring.
This transfer makes it possible for the offspring to have better survival chances, which Darwin
describes as “survival of the fittest”.
The trait version of an individual and the number of gene duplicates passed on to next
generations aid the species in thriving more. In this case, an individual has higher chances of
reproducing species who survive future generations, if more offspring are reproduced with the
specific gene or mutation.
Natural selection is significant to humans since it facilitates in offering the Homo sapiens
species the best mutations possible for survival. One instance of Natural Selection’s is important
in humans is the opposable fingers and thumbs. In the past years, the human ancestors have
possessed the gene of “opposable thumb”, making it possible for the current humans possess
opposable thumbs. This feature has played the role of helping humans hold and utilize objects.
Individuals with this feature endure and pass their DNA to their offspring, who end up having
the same mutation, thus surviving off predators and competitors. Another instance of natural
selection which is more specific and recent is an infection like The Plague. This infection saw
the death of millions of people due to lack of a mutation that was possessed by others who
survived the disease. Th...
