- Life Blueprints: Evolution
Evolution is seen by many to be the biological change in organisms over a period of time. Over time, evolution has been the cause of change at a genetic level, with each generation; these changes can slowly alter physical attributes of a whole species. The theory of evolution is a means to explain the growth and development from sign of first life or the first cell which appeared 3.85 billion years ago (Biologos, 2015). For example, as humans, going back several million years- before even the stone age, ancestors would still have features such as two eyes, two ears, some extra hair and arms and legs. They would be better at things such as climbing trees than the modern generation (Strange Science, …show more content…

Charles Robert Darwin, born in 1809 in England was best known for his work as a naturalist, explaining biological change through a developed theory of evolution (Wikipedia, 2015). Though Darwin didn’t discover evolution, he brought about change through his revolutionary theories. Darwin’s most famous theory is known as the theory of Natural Selection. Darwin specified five theories under this topic which must work together in order for Natural Selection to transpire. The five theories included firstly, evolution which is based on the fact that species change as they exist. The second is common descent where organisms have diversified from one or several original stock that they have …show more content…
Lamarck was of French nationality and became interested in natural history shortly after assisting the French force in the late 1700’s(Wikipedia, 2015). Lamarck had three main theories which reinforced the other. These main theories were known by the titles of; Change through use and disuse, organisms driven to greater complexity and, evolution by natural processes. The theory of ‘Change Through use and Disuse’ was largely based on the fact that as environments changes, as did the living organisms in order to adapt and ultimately survive. An example of this is the evolution of a giraffe. Many herbivores would scavenge among the lower plants, however as a giraffe stretched its neck in order to reach the higher florae, a “nervous fluid” would flow into its neck and eventually elongate the neck. This is also what would happen but in reverse if an organ or limb was not used as frequently. The next theory of ‘Organisms Driven to Greater Complexity’ was surrounding the philosophy that nature would drive organisms inevitably upward, creating additionally complex ones, and that life began through a extemporaneous generation. The final theory of Lamarck’s was commonly known as ‘Evolution by Natural Processes’ addresses the concept of life’s current form being taken on by natural processes rather than phenomenal interferences. This stumped British naturalists mostly as they primarily
