Essays on Evolution

The evolution of Hominins has been through a number of stages which are a major influence on skeletal changes. In all the stages, Hominin’s behavior was adapted to various modes of survival. Before the bipedal walking and the upright posture, the hominins practiced terrestrial quadrupedalism, Orangutan-like climbing, and suspension, monkey-like...

How human variation has influenced their adaptation to survive in the past and present world             Variability is inherent in all living species, and it is enhanced by environmental and biological procedures. It plays a significant role in certifying the strength of species as well as their capacity to acclimatize to...

The possibility to walk on two legs was the most popular trait in the hominid lineage. Bipedalism established the distinction between the first hominids and the other apes although big brains were previously thought to be the unique feature.             There are several factors which prompted humans to become bipeds based...

Evolution Evolution refers to the gradual process of heritable change within a given period among humans. During the evolutionary process, living organisms, cultures and languages respond to the changing circumstances, and they become more sophisticated and adaptable over time. As a theory, evolution is lauded as the best concept that explains...

Marine biodiversity might be seen or classified as a universal public good. The grounds for this include the fact that it cannot be achieved at the national level. In other words, this would result in the preservation of genetic diversity, on which future evolutionary evolution is dependent, as well as...

Genetic Inheritance and Organismal Evolution Genetic inheritance, which determines a person's race and biological make-up, is what gives humans their biological differences. Human characteristics are handed down to the following generation through a process of natural selection known as genetic inheritance. The slow alterations that develop over time are what lead...

Introduction Carl Sagan's 1977 book The Dragons of Eden: Speculation on Human Evolution is a work of science fiction. A variety of sciences, including anthropology and evolutionary biology, are used to try to explain the evolution of human intellect (Sagan 3). The author addresses the question of quantifying human intelligence capabilities....

One of the crucial processes in an organism s ecological and evolutionary effects is dispersal. In essence, because not all living things can disperse, seeds are created and must be transported by a vector to a new location (Reynolds, 2016). The propagules can then be carried to other locations by...

The development of technology in recent years has given rise to several discussions on how to control how much media exposure young people receive. Children are also affected psychosocially, which affects how they interact with their environment and others around them (Christakis). By focusing on the fact that media has...

Genetic inheritance, which determines a person's race and biological make-up, is what gives humans their biological differences. Human characteristics are handed down to the following generation through a process of natural selection known as genetic inheritance. The slow alterations that develop over time are what lead to organismal evolution. These...

The Notch Signaling Pathway The juxtacrine or contact-mediated signaling pathway between two neighboring cells is used by the Notch Signal Pathway. During the selection of cells' fates and the development of the embryo, this kind of signaling is required (Kopan 2012). The intracellular domain that controls gene expression is released by...

As an immediate response to the selection of certain organisms and new habitats, evolution changes rapidly. An environment's overall conditions may be impacted by such changes. Parallel evolution occurs when identical features respond to identical population pressures and mutations, and this eventually results in changes to an organism's phenotype, or...
