Evolutionary Relationship between Humans
and Their Environment



evolutionary theory is evidently becoming irrelevant in the modern scientific
world, and its supporting evidence is becoming obsolete due to the current
relationship humans and their environment. Humans have elevated themselves
above nature and developed adaptive means of removing themselves from evolution
and natural selection. The principles of inherited variation and natural
selection are not dominant in the twenty-first century, due to the forces of
evolutionary changes caused by technology, the environment, and the social

The process of
evolution is no longer a natural selection phenomenon. As Weiner (1995) argues,
it is not just a theory about changes happened in the past, but something that
we can watch, because it goes on all around us all the time. As such, scientists
are modifying current living conditions and creating new technologies based on
the Darwinian evolutionary theory. For example, the aspect of natural selection
involving the elimination of individuals with weak immune systems and
preserving those with strong immunity to survive in endemic malaria regions is
becoming irrelevant. Medical scientists have introduced drugs that boost one’s
immunity to increase adaptability to a given environment by acquiring mutated
genes, which is a distinct characteristic of evolution (Weiner, 1995). Technology has led to improved housing and
clothing facilities. Modern homes rely on environmental cleanliness and energy
efficiency. On the other hand, dirty clothes and body odor harbor bacteria and
fungi that cause skin infections. The improved hygiene, through advanced
technology, is achieved by studying the principles causing natural selection
and variations among human beings.

Regarding the
environment, humans are altering the biosphere, resulting in genotypic
divergence of many species (Weiner, 1995),
such as the disease-causing vectors. The study of factors influencing changes
in the environment and ecosystem, such as pollution, radioactive emissions, and
human illnesses is establishing improved control methods. The disease-causing
organisms reproduce well in unhygienic places and mutate to increase their
chances of survival. Through the understanding of Darwin’s natural selection
principles, the human being is controlling the environment through modern
synthesis; hence making it unfavorable for phenotypic divergence and adaptation
of microorganisms (Weiner, 1995).

Moreover, humans are
using natural means of balancing the ecosystem. For example, biological
scientists utilize biological control to chemical control in the management of
pest and disease-causing organisms. As such, the former balances the energy
flow in an ecosystem by maintaining producers, consumers, and decomposers in
the food chain of an ecosystem. Darwin’s theory of natural selection enabled
researchers to control the organisms in the environment without destabilizing
the ecology. Scientists are nowadays selecting them to live, even without
undergoing evolutionary changes. The elevated role of human beings is
establishing highly adapted organisms that fit for their current environment. Although
the unicellular organisms are undergoing natural evolutionary changes, the
multi-cellular ones are not experiencing any alteration or genetic inheritance
of adaptive genes. The only evidence of change is in the genetic makeup, which
enables them to be more adaptable to the current environment (Weiner, 1995).

Climate change is
another factor that altered the evolutionary relationship between humans and
the environment. For instance, global warming increases temperatures on earth’s
surface by trapping greenhouse gases. Humans play a significant evolutionary
role in climate change. Global warming elevated humans above nature causing the
development of adaptive genes to live in high-temperature areas. The evolution
taking place among them is no longer natural, but it is induced through climate
change. The result is the development of adaptive features in living organisms
with an aim of exploiting the human-modified ecological niche (Weiner, 1995). For instance, humans are
undergoing genetic variation and new mutations due to increased trapping of
greenhouse gases (Weiner, 1995).
Moreover, the melting of snow on the ice caps, rising of sea levels and the tropical
storms are all due to climate change. The ecological effect is evident from the
compulsion faced by polar bears to change their feeding mechanism to
cannibalism. The temperature increase is a result of humans elevating
themselves above nature leading to genetic variations in their offspring in
favor of heat tolerance. The process of civilization generated a different
evolutionary path for better adaptations in hot environments caused by global

Humans have
differentiated or elevated themselves above nature based on their adaptation by
various means to remove themselves from the forces of evolution and the process
natural selection. They have created their setting and are trying to
communicate with and explore other worlds. As a result, humans have become far
too unnatural or induced in this social, environmental, and technical
