Charles darwin and the theory of evolution essay

There are two major components in Darwin's theory of evolution: The "theory of descent with modification" or "theory of evolution by common descent" essentially postulates that all organisms have descended from common ancestors by a continuous process of branching. In other words, all life evolved from one kind of organism or from a few simple kinds, and each species arose in a single geographic location, from another species that preceded it in time. Evolutionists have marshaled substantial evidence for the theory of descent with modification.

Evolution and Charles Darwin Evolution I. Evolution is the most important concept in all of biology. None of biology makes sense except in the context of evolution.

Introduction to Evolutionary Biology

Just why is evolution so important to biologists? Evolution makes sense of the similarities and differences and provides a rational explanation for the distribution of taxa.

It also supplies explanations for the sometimes wild exceptions we see eg cacti and euphorbs, which look so similar but are clearly only very distantly related to each other.

The explanation is convergent evolution. Comparison of DNA and protein sequences only makes sense in light of evolution. Our understanding of infectious organisms and our tactics to combat them are entirely based upon understanding of evolution.

No idea comes from thin air. The historical perspective helps to understand where the concepts behind evolutionary theory came from. Here are some of the basic historical issues. The typical view of the nature of species at the beginning of the nineteenth century is often described as the Doctrine of Fixed Species.

This concept had its primary roots in Greek philosophy: During the eighteenth century, Carolus Linnaeus developed the basis for our nested, hierarchical classification system, or Taxonomy. The geologic discipline of stratigraphy was developed during the late eighteenth and early nineteenth centuries.

Charles Darwin & the Tree of Life

Though this accomplishment was shared by many geologists throughout Europe, the name most commonly associated with developing the concept of stratigraphy is William Smithwho was an engineer engaged in building canals all over England.

George Cuvier eventually Baron George Cuvier was a scientist of the late 18th and early 19th centuries. His specialty was vertebrate anatomy. Because of his expertise in anatomy, Cuvier was the obvious person to ask to examine strange remains found during reconstruction after a major Paris fire.

These remains turned out to belong to extinct organisms, and led to the development of the field of study we call Paleontology. Cuvier was the first to reconstruct dinosaurs.

Cuvier is also remembered for coming up with the concept of Catastrophism, as an attempt to reconcile his religious beliefs with the evidence he discovered as a scientist.History: Theory of Evolution by Charles Darwin - Charles Darwin’s theory and evolution Introduction: Charles Darwin was an English scientist who developed the theory of evolution which had been around for long period of time which gave him fame during his life and after his death.

Common Misconceptions about Evolution

Darwin () believed that whales evolved from bears based on a scenario where selective pressures might cause this evolution, but he was criticized for this idea and removed the suggestion.

Gould, ) Today, there is much more fossil evidence for the evolution of many species thus supporting the idea of evolution as a general biological principle, including the evolution of whales from lower animals.
