The Definition of the word "Evolution"
The definition for the word “evolution” has a very broad meaning. Evolution can really be applied to anything; plants, animals, bacteria, social behavior, agriculture, human health, medicine, and so much more. In my own words, I would describe evolution as a process for species to adapt or modify into a more complex form. This modification allows for the species to adapt better to their environment. Whether that be a gradual development, or something that happens over centuries, evolution is an ongoing occurrence, in my opinion. There are many aspects that can explain the reasoning by evolution, which I will go into small detail about a few. The study of fossils, also known as paleontology, provides direct evidence of species from past life and it also shows a descent of organisms with common ancestors. Studying fossils can help explain about extinct as well as current living species today. This can also give scientist a theory on how the modification of these species has changed over time, and maybe gives a reason why. I believe evolution happens to help a species thrive more in their environment. It is no question that life is organized hierarchically with organisms, populations, communities, ecosystems, and more. As species interact with their environment, different traits will contribute more in order to survive. This could explain why the beaks of birds differ in each environment, or the color of fox fur in each climate.
I believe that to an extent evolution is a theory, but also a fact. There is clear evidence that species change over time, which is the definition of evolution. Evolution can be proved through phenotypic evolution, phylogenetic relationships, paleontology, and so much more. And I understand why there is such a hard argument between the relationship of evolution and fact or theory. But I more personally fall into the reasoning of theory. Stating something is fact automatically rules out any other possible explanation, since it has been proven repeatably and all agree. Explaining that evolution is only a fact would rule out any possible outcomes or reasonings. There would be no need to go more in depth on research of evolution, but stating it is a theory can imply that there is still more research to be discovered. More discovery of science and evolution is still being brought to light today with the advancement of technology. It is quite exciting to see what more can be discovered about biology and evolution as technology continue to advance.
Hi Georgia! I really like how you first explained everything that evolution can apply to. When writing my blog post, I jumped straight into the definition and did not even think about these sorts of things. I have interest in agriculture and human health, but I have forgotten how important evolution can be to these things. I enjoyed how you used examples, such as paleontology, to show that there is a lot of solid evidence for evolution. I agree that evolution is both a theory and a fact because there is a lot of evidence, but also more things to be discovered. Your post is very thorough and you seem to have a very good idea of what evolution is about!
ReplyDeleteI like how you talked about using evolution to explain the history of certain species and how some might have gone extinct. I personally had only thought about how evolution might impact the future of different species. I also like how you mentioned the hierarchy that life is organized into. I enjoyed reading what you said about evolution being fact or theory. Stating it as a theory leaves space for other theories or discoveries to be made. I wholeheartedly agree with your statement that evolution is a mix of fact and theory. Great post!
