Alternative Theories Of Evolution - Is Charles Darwin's Theory Of Natural Selection Wrong?

Check out these Alternative Theories Of Evolution! Charles Darwin's theory of evolution is widely seen as the most accepted theory of human evolution, but is natural selection actually real and could these other theories like the one from jean baptiste lamarck be on to something?

Lamarckism Lamarckism was one of the earliest theories of evolution and was first proposed by Jean-Baptiste Lamarck in 1809, hence the name. The difference between it, and the commonly accepted theory put forward by Darwin is that Lamarck suggested animals could develop new traits within their lifetimes, as opposed to across a number of generations, and then pass them on. 9. Anaximander’s Theory of Evolution Anaximander was a Greek philosopher who lived between 610 BC and 546 BC. If history had turned out differently, he could have been more famous than Aristotle. As well as being one of the first to create a philosophical view of the world, he believed that the inhabited parts of the planet were on a flat surface of a cylinder, and he created one of the first maps of the Black Sea… he also developed one of the first known theories of evolution- one that was quite similar to that of Darwin’s. 8. Orthogenesis While Darwin’s theory of evolution shows that random mutations cause changes in animal physiology, and those that are beneficial tend to remain across generations, Orthogenesis, which is also called ‘straight-line evolution’ suggests that each successive generation of a species evolves in a single, definite, direction. 7. Saltationism Saltationism was a widely held belief of evolution before Darwin proposed his theory. While Darwin put forward the idea that species evolve gradually with mutations passing on through generations by natural selection, saltationism is the idea that large mutations happen, which lead to big changes happening much quicker. 6. Theistic Evolution A major problem that some people have with Darwin’s theory of evolution is that it implies that animals evolve in a random way, but this falls at odds with the idea that there is a God, or a creator, who surely would have designed perfect animals in the first place. 5. Vitalism Vitalism is the idea in biology that living organisms are fundamentally different from non-living structures because they either contain a non-physical element or are overseen by a different set of rules. Often this is referred to as a ‘vital spark', or a ‘soul', and there are some who believe it works hand in hand with evolution… with the belief that life goes through stages of actively wanting to evolve, as opposed to Darwin’s theory that says evolution is continually happening randomly at essentially the same rate. 4. Structuralism While Darwin's theory of evolution is functionalist, where organisms adapt to changing environments without a pre-arranged plan, structuralism is the idea that there are pre-ordained frameworks in place that direct the changes that occur, in particular, the effects of physical forces on development that in some cases supersede the idea of natural selection altogether. 3. Catastrophism We can see from the fossil record that, throughout history, the number of animals and plant species on the planet has varied drastically. Many believe that this was due to natural ebbs and flows, but the theory of catastrophism has been put forward to help explain this, and also to help understand its effect on evolution. 2. The Neutral Theory of Molecular Evolution First suggested in 1968, the neutral theory of molecular evolution says that at the molecular level, most genetic variances that occur in populations don’t happen as a result of natural selection, but because of random genetic drift. A species of animal may, for example, contain various genetic codes that perform the same function in different ways, but none of these are necessarily better or worse at what they do. 1. Ape Theory Why do you think that humans have evolved to become seemingly more intelligent and able to communicate better than any other species? Is it random evolution, divine intervention or, as was suggested in 1992, was it because our ancestors discovered psychedelic mushrooms on their journey?
