Speciation

Evolution is the change in heritable characteristics of biological populations over successive generations. It is the process that gives rise to variation in existing populations, drives speciation, and what leads to the extinction of new species. It is the natural change that occurs in response to environmental pressures resulting in phenotypical changes. Another way for phenotypical changes to occur in a species is by human intervention. Domestication is a form of human intervention. The…

The killer whale or orca is another name for species Orcinus orca. It is a toothed whale that belongs to the family Delphinidae in the order Cetacea.. They are found globally in all oceans. In fact, after man they are the most widespread mammal in the world. Killer whales live in pods. The structure of the pods are usually matrilineal. This means that the offspring wait with their mother throughout life.The individuals in a matrilineal group travel closely together. The killer whale worldwide…

Heredity and Evolutionary Theory Charles Darwin, a naturalist and geologist held the belief that all living things share a common ancestor. This statement is in relation to his contributed Theory of Evolution that has greatly impacted the world’s view about the human originates. Evolution is defined as change over time and according to Darwin, this process of which all diverse kinds of living organisms have developed into their own branches is due to natural selection which grants the organism…

Kai Wilkins Dr. Makin Criminal Justice 205 1 October 2015 Insight to The Criminal Justice System Guenther’s Views In a time before what the world has become today, Guenther had many philosophies and ideas on how the criminal justice system should be ran. Guenther believed in 1976 that the system was more “unfair, harsh, and biased” and could seen more as a criminal processing system. What he found was that it the system is just and true, there were several incidents he went through…

evolution as a result of unequal crossover and gene conversions among gene copies. I examined gene conversion events among Angiosperms, and identified different patterns in different subfamilies. I detected simple duplication events followed by speciation in Solanaceae, loss of gene copies in Grass, and old gene duplication followed by independent gene conversions in different two clades of Brassicaceae. However, these observed gene conversion events differs from the expected evidence of…

points, hold strong through years of testing, the discovery of evidence, and the disproving of other theories. Evolution was first proposed by Charles Darwin in 1859, in his book “On the Origin of Species”. He stated his ideas on adaptation, speciation, and natural selection, and how they all tied together into evolution. He stated multiple forms of evidence, albeit them not being very…

Most palaeontologist’s agree that hominids first evolved in Africa, but disagree where Homo-sapiens emerged and this caused the origin of the modern Humans to be a fervently debated topic in Palaeontology and Anthropology. There are two theories currently regarding the origin of the modern-day humans: 1) They emerged in one place which is Africa and then migrated elsewhere which is the “Out of Africa Theory” and 2) Is that Hominids spread out of Africa and evolved worldwide which is the…

According to the recent studies, Shrimp aquaculture is considered to be one of the most environmentally destructive forms of modern agriculture affecting mangroves directly [83]. Aquaculture destroys the mangroves to create shrimp ponds, reduce the ground water levels, and cause pollution to the surface water from the pond effluents [100]. Lack of long-term conservation and management of natural resources are the greatest shortcoming of shrimp aquaculture [40]. Researchers have noticed that the…

The Great GMO Debate Introduction: Gmos have been introduced since the 1970s, and they have taken place of our main food supply. Although the creations of Gmos worry citizens about the unknown process of mutating our food supply these are just incorrect accusations while Gmos are beneficial for the stability of our society. The Debate on the Safety of Genetically Modified Organisms: In the last few decades Gmos have be introduced in order to fulfill our cultures supply needs for food.…
