The key to understanding Biology is through the study of Evolution[1]. Evolution is what makes life possible[2]. How life started and how life came to be is all through the process of evolution. Evolution can explain how complex organisms came to be, how simple forms stay simple, and how organisms are related to each other. Evolution not only explains the development of visible morphological characters. At the molecular level, functions and forms of genes are influenced by the process of evolution as well[1]. To further understand how evolution is the heart of life processes, we need to understand the concepts and ideas that explain life: the theories of evolution. History of Evolution Before the conception of evolution, people believed in the paradigm of the   ' Fixity '   of species[4], that everything was created through Divine Conception [5].   The accepted idea is that every single organism was created as it is, nothing is mutated, everything is unch...

Predation is when an organism kills and eats another organism (prey) to gain energy necessary for reproduction. In the perspective of the prey, predation reduces fitness. Predation is therefore a type of antagonistic interaction, a biotic factor limiting species distribution [1][2]. However, predation is also important to promote biodiversity through adaptation[3]. Types of predation 1. Carnivory - a type of predation where one animal consumes another. Carnivory is obviously displayed by large animals. Examples of these are wolves hunting moose, eagles hunting monkeys, cats hunting mouse, etc. Another form of carnivory is group predation. This is usually observed in ants and spiders as well as social carnivores such as lions and hyenas[1]  where a group of individuals of  the same species are feeding on one large organism . Plants can also become carnivorous predators. Although they are not mobile, they are still able to capture animals. Examples of this is the...
