What Did Darwin's Natural Selection Provide?

Darwin 's Evolution by Natural Selection

Darwin 's Evolution by Natural Selection
Charles Darwin is known in the science community as one of the pioneers of the theory of evolution. While many people believe that Darwin founded the theory of evolution, he actually didn’t. The theory of evolution actually dates back to the ancient Greeks. Greek philosopher Anaximander actually began the theory of life developing from non-life and the gradual evolution of man from animal. However, Darwin brought something completely new to some of the old evolution theories. That new additive became known as Natural Selection.
Charles Darwin’s education at Cambridge University actually knew him as a God loving man. Firmly believing in
Here we can look at Darwin’s voyage upon the HMS Beagle and his encounter with finches in and around the Galapagos Islands off the coast of South America. While on the mainland of South America, Darwin observed a type of finch inhabiting the area. Darwin studied the finch specie and tried to look for different variations, but to no avail. Darwin observed no changes in the finches while on the mainland. However, this was not the case when he started exploring the Galapagos Islands. Darwin was quick to notice a variation in the species of finches, particularly in their beak area. The amazing part was that the finches were actually different from one island to the next. Darwin quickly related this variation to the environment and theorized that the difference was due to the fact that the finches had to adapt to the different environments on each of the islands and the mainland. Darwin felt that the original finches migrated to the islands and then dispersed throughout them. This caused them to encounter different types of environments and different types of food sources. Darwin was quick to conclude that the variation in the size and shape of the finch’s beaks were due to their difference in diets and how they had to hunt and eat their food according to the environment that surrounded them. This survival behavior lead Darwin to believe that over time the finches changed anatomically in order to survive and
This outcome could then cause more of that outcome among the population.
Migration: This is when some species of a certain population join the population of another species. This movement can over time become more frequent.
Genetic Drift: This mechanism happens when a certain population of species has offspring that survive and are able to reproduce. On the other hand, another population of species were killed by a more dominant specie; i.e., human being. The end result would cause the killed population to have less population in future generations.
Natural Selection: In this mechanism, population 1 is more noticeable to bigger prey making them easier to eat. Population 2 is less noticeable making them more able to reproduce. Population 2 then passes their unnoticeable gene down to their offspring, which in turn makes population 2 more common then the previous generation.
Today, as modern science advances daily, more and more information and theories are contributing to the pro’s of evolution and the con’s. Charles Darwin will forever be remembered as a scientific pioneer who initiated and implemented one of the most well known theories in science today. His work continues to inspire scientists of past and present, and his work has laid the foundation for many theoretical works in the science field
