Running head: BIOLOGICAL BEGINNINGS
This paper will explore the concept of biological beginnings. The first area of this topic to
be covered will be the evolutionary perspective. Under the dimension of evolution, the
foundations of human resilience and survival will be explored. The fact that humans have been
among the longest surviving organism shows that they have been able to withstand all the
challenges that have led to the extinction of many species. The next sections of the paper will be
dedicated to genetic foundations. Every human being has unique genetic instructions that shape
their growth, life, and traits. The relationship between genes and chromosomes will then be
explored. Chromosomal abnormalities are also going to be discussed. Environmental influence
on gene expression is an important aspect of this topic, and thus some section of the essay will
also be dedicated to this. Lastly, a summary of the whole topic will be provided.
According to the evolution theory, humans have taken over millions years to evolve. It
is believed that about 98% of human ancestors originated from African Savannas. The human
mind is shaped by the pressure to survive and reproduce. According to this perspective, humans
have a more extended childhood period than most of the other organisms, and this allows for the
development of a larger brain compared to them. In other species, the young ones are born and
start to become independent within a shorter period. For example, a newborn calf starts walking
immediately. Though she may experience some walking problems due to having underdeveloped
limps, she quickly becomes strong and within a few days she can walk comfortably. However, a
human child starts walking at least 1 year after birth.
Humans evolved to survive in a complicated society through natural selection. The
natural selection is an evolutionary process, defined by Charles Darwin, where species adapt to
the environment for survival and reproduction (Hall, Griffiths & McKenna, 2013). The adaptive
behavior promotes the survival of an organism in the natural habitat. For example, the adaptation
of polar bears to the Arctic regions, which is different from the adaptation of grizzly bears,
shows how natural selection works. Grizzly bears have adapted to ...
