What Is Evolution? Essay

324 words - 2 pages

Evolution is an unpredictable and natural process of temporal descent with genetic modifications that is affected by natural selection, chance, and changing environments. An easier more simplified definition is a change in the gene pool of a population over time. A gene is a hereditary trait that can be passed on for many generations.The gene pool is the set of all genes in a species or population. In order to understand evolution, it is vital to view ...view middle of the document...

Individual organisms do not evolve; they keep the same genes throughout their life. When a population is evolving, the setup of different genetic types is changing. Each single organism within a population does not change. The process of evolution can be summarized in three simple steps: genes mutate, individuals are selected, and populations evolve.Evolution can be divided into microevolution and macroevolution. The kind of evolution listed above is microevolution. Greater changes, like when a new species is created, are called macroevolution. Some biologists think that the workings of macroevolution are different than the ones of microevolutionary change. Other people believe that the distinction between the two is irrational, macroevolution is cumulative microevolution.The word evolution has a variety of meanings. The fact that all organisms are related by descent to a common ancestor is usually called evolution. The argument of how the first living organisms came about is usually called evolution. This should be called abiogenesis. Very commonly, people use the word evolution when they really mean natural selection (one of the many workings of evolution.)

Compared to the humans, they had powerful jaw muscles that were used for a specific purpose. On the other hand, humans lost this sequence 2.5 million years ago. Some suggest that because of the changes in what we eat, accommodations in the DNA sequence were made. This idea correlates to the fact that

evolution Essay

633 words - 3 pages . Evolution is not a fact, but it has been observed very carefully. Scientists have observed microevolution of HIV virus mutating to be resistant to drugs, and macroevolution of entirely new species of mosquitos and plants. Scientists have directly observed every aspect of evolution, therefore it is a fact that species have evolved. Evolution is a fact when describing what happened. Evolution is a theory when describing how it happened. Some may be confused how evolution can be a theory and a fact. Another example of this is Gravity, which is also a theory and a fact, that objects with mass gravitate towards one another.

The genetic code of an organism can be changed when it is passed on to offspring. Mutations can occur when this process happens much like the hammer head shark’s head. These mutations can either thrive and create a better organism
