AGAINST NATURAL SELECTION: A species is an entity that has temporal
(time) and spatial (geography) dimensions. So an expanding population/species
covers more and more geography over time, and so on. I think what is usually
meant by “humans” is humans in this modern world of medicine and dominance over
the environment, etc. In particular, it means humans as a population not
subject to scarcities of food, ravages of predation, and suffering by disease.
This is because in many people’s minds evolution roughly equals natural
selection and its effects, and natural selection roughly equals these listed
aspects of the environment and their effects. The struggle for existence, the
competition for food, and so on. And the struggle is over. The other biggie,
sexual selection, is often left out of the discussion. The popular mindset
often seems to lack a concept of human mate competition or mate choice as
factors in human evolution or human affairs in general. I think this is due to
modern conceptions of monogamy. We fool ourselves into thinking that since
there is the same number of men and women. and everybody eventually gets married
to a member of the opposite sex, etc. , then there really is no mating
competition or sexual selection. (Not true, not true, and not true.) This is a
deeply fascinating set of assertions, beliefs, fallacies, and innuendos. Almost
everything in evolution is about food and sex. If we have removed with modern
medicine, agriculture, and deadly weapons the parasites, predators, and food
limitations from our environment, that does not mean that we are not evolving.
What it means is that a large number of selective forces have shifted. Since we
are talking mainly about stabilizing selection related to the ability to find
food, avoid predators, etc. (maybe some directional selection as well), this
mostly means that we are experiencing “relaxed selection.” http://webcache.googleusercontent.com/search?q=cache:GwJWCO_aqCsJ:scienceblogs.com/gregladen/2009/08/24/humans-are-no-longer-subject-t/+&cd=8&hl=en&ct=clnk&gl=au

FOR NATURAL SELECTION: The findings suggest that about 9 percent
of the human genes examined are undergoing rapid evolution. "Our study
suggests that natural selection has played an important role in patterning the
human genome," said Carlos Bustamante, a biologist at Cornell University. A
separate study announced last month indicated the human brain is still
evolving, too. Compared to chimps, Bustamante's team found that the genes most
affected were those involved in immunity, sperm and egg production and sensory
perception. A comparison between human and chimpanzee genomes found that these
genes have undergone more changes in humans than in chimps, despite the fact
that the two species shared
a common ancestor some 5 million years ago.

Charles Darwin explores the idea of natural selection in particular survival of the fittest.   Many scientists are on debate about this issue some claiming that the evolution of humans has ended and others claiming that is slowly still occurring.

Over time evolution has been a big part in the development of the human species

# data[].attributes.body
There are new selection pressures for us to adapt to– technology, pollution, UV radiation, electromagnetic radiation from electrical devices

# data[].attributes.body
Natural selection or another phrase for it, the survival of the fittest is when organisms have the most adaptive characteristics therefore allowing them to survive and pass on these useful characteristics generation to generation.

# data[].attributes.body
Natural Selection is a natural process that results in the survival and reproductive success of individuals or groups best adjusted to their environment and that leads to the perpetuation of genetic qualities best suited to that particular environment. In other words, a process by which plants and animals that can adapt to changes in their environment are able to survive and reproduce while those that cannot adapt so not survive.

Natural selection relies on the
survival of the fittest. Yet, modern medicine is interrupting this process and
effectively stopping our species from evolving. Some argue that this leaves our
species vulnerable to extinction at the next significant environmental event.  You are to provide justified arguments for
both sides of the debate, and then conclude by deciding which group of
scientists provide a more credible argument. Justify your conclusion.
