Essays on Evolutionary biology

Homeotic complex (Hox) genes are defined as a group of related genes that specify the anterior-posterior axis and segment identity of metazoan organisms during early embryonic development. These are situated very close to one another on the chromosome in groups of clusters. The orders of these genes located on the chromosomes are the same as…

The species I will be discussing is Alopex lagopus whose common name is Arctic fox. The Arctic foxes are located in the Arctic region and they live in the areas around the North Pole which is characterized by long durations of snow cover (Blix, 2005). The trait I will be discussing is fur coloration. The…

What is a gene?According to the national institute for health and ‘TheBody. com” a gene is a unit of heredity.  The gene represents the smallest collection of DNA that can be demonstrated to transmit characteristics (traits)  to an organism’s offspring.Both sites are well established bodies involved in the science of physiology and health fields dealing…

Through years of evolution, most animals have evolved their own unique defense mechanisms, enabling them to survive effectively in the wild. The squid, a member of the Mollusca class Cephalopod, is a prominent example of evolution by natural selection to adapt to new environments. The newfound predators that hunt by speed and eyesight will be…

Altering this extended phenotype, or ability to build bowers resulted in no change of mating, but males that built successful bowers showed to be less aggressive with other males in the population. This is important in maintaining polymorphic populations (Measles, 2014). In my self-created scenario, the focus is on the small male population of child…

Many important contributions have been made to science. One of the most important deals with the theory of evolution. Back in the 1800s, a man named Alfred Russel Wallace made his contributions to science and to the theory of evolution. His discoveries influenced the world of science in the years to come. One of the…
