Here’s a snippet of the essay.
Every living organism in the planet has changed in one way or the other from its original for. Organisms change in their genetic make up, and their physical characteristics to ensure their survival in the ever-changing environment.
The term evolution is derived from a Latin word evolution, literally meaning unfolding or “rolling forth”. It refers to change through time. Biologically, evolution may be defined as the change in the genetic make up of a certain population over a long time (Haviland 2011, 74). The theory of evolution was first published in 1859 by an English naturalist Charles Darwin the Origin of Species. In this theory, he posited that all living organisms have a common origin (Darwin 2004, 36). Genes are the basic units that of heredity that determine the genetic traits of organisms. They are passed from parents to an offspring, from a generation to another. Evolution may take place through adaptation or speciation – (Haviland 2011, 74). Adaptation can be defined as the sequence of crucial adjustments of living organisms to their ecosystem. Speciation on the other hand, refers to the phenomenon of species multiplying, giving rise to multiple decedent species.
Theory of Evolution
The theory of evolution was formulated through robust research that took Charles Darwin over five years (1831 – 1836) to gather evidence (Darwin 2004, 05). Aware that this theory would provoke a myriad of controversies in the religious domain; Charles delayed publishing his findings. Over two decades after the research, Darwin published his findings in the Origin of Species and Natural Selection. A few years after Darwin published his masterpiece, a catholic priest Gregory Mendel released results of experiments carried out in over 2900 pea plants in a vegetable garden. The results revealed that inheritance of biological traits would be determined by “factors” or “units” that would be passed on among descendants unchanged. Later, he established that the factors could not show in the physical characteristics. However, they would be passed to subsequent generations. These “factors” would later be termed as genes. Mendel’s finding formed the basis of laws biological inheritance. This significant contribution labeled Mendel as the father of genetics (Haviland 2011, 76).
The Mendelian laws would be based on the physical characteristics such as texture and texture of peas. Further research would later be carried out using powerful microscopes; his inferences concerning the mechanism of inheritance would be confirmed through the discovery of molecular and cellular basis of inheritance. Chromosomes would later be discovered in the 20th century; they would be perceived to contain genetic information. With the combination of Mendelian genetics and Darwin’s theory, a group of botanist, biochemists, and zoologists formulated a theoretical model known as The Modern Evolutionary Synthesis. This Neo-Darwinist theory posited that evolution is a gradual phenomenon based on environmental adaptation, and little genetic changes within a geographically separated population after several generations of natural selection (Haviland 2011, 77). Later, the DNA would be discovered as the units that carry genetic materials. This is how the theories of evolution came to existence (Maynard 2007, 58).
How Does Evolution Take Place?
Evolution occurs through two interrelated phenomenon; adaptation and speciation, as earlier put, species may modify their phenotypes over time to be able to thrive in their immediate environments. Speciation also contributes to evolution through the process by which a single species brings forth descendants of the same species. Essentially, evolution occurs through mechanisms such as Natural selection, mutation, sexual recombination, divergence, convergence, among other evolutionary principles (Maynard 2007, 08).
