The Theory of Evolution:
The theory of evolution in natural selection was first proposed in the early 19th century by Jean-Baptiste Lamarck (1744-1829) where he fully formed a theory that comprises of ideas that living creatures are not passively modified by their environment. Instead, a change in the environment creates adjustments depending on the needs of the organisms of which leads to a change in their behaviour, driving the Lamarkian evolution.
A development that this theory has gone through includes the fact that Lamarck's mechanism for evolution was modified by Charles Darwin (1809-1882) theory of evolution since, Lamarck's ideologies has been contributed in his Darwin's first book dealing with natural selection. To justify, Lamark's theory has been adjusted into focusing on the inheritance of acquired traits where traits changed or acquired over a persons lifetime could be passed down to its offspring. This is different compared to Lamarck's first theory where the environment creates changes depending on the needs of the organisms.
A challenge that scientists has faced is to explore fully justified evidence of Lamarck theory that this occurred through use and disuse. If an animal usually used a specific trait/characteristics, that trust would become larger or more pronounced. If that trait went unused, it would no longer develop fully and would become reduced.
Some method of questioning were developed that reached new conclusions like how the inheritance of acquired traits has been disproved by advances made in the past century in the field of genetics. Thus reaching to genetical discoveries such as mobile DNA, transposons, symbiosis, horizontal gene transfer, regulatory elements, gene duplication and chromosome rearrangements. These new discoveries have changed the theory of evolution since it integrates Darwin's ideologies with major breakthroughs in biology over the past 50 years.
There is no doubt that a theory comprises of thorough logical explanations of why certain aspects are the way they are similarly to Lamark's theory that focuses on the inheritance of acquired traits where traits changed or acquired over a persons lifetime could be passed down to its offspring. In contrast, a scientific law is predicting the outcomes of certain initial aspects similarity to predicting how far a baseball travels when launched at a certain angle through the use of a specific law in psychics. To justify, a law is the speculation of what happens whereas a theory like the theory of evolution, proposes reason/ answers why it is the way it is. Further more, a theory does not grow into a law however; the evolvement of one usually triggers development on the other. In the 17th century, Johannes Kepler theorised cosmetic musical harmonies to explain the nature of orbits, he developed three brilliant laws of planetarium motions while he was studying the motion of orbits in an effort to support his theory. While his laws were appreciated in the scientific field, gravity replaced his theory of harmonics to explain planets motions. This proves my point that laws resist change as we revise them to suit our needs and development of knowledge. A theories acceptance however is competitive between scientists since the most successful theory is usually the one with the most explanation to it. As evident, the Periodic table was largely accepted due to its discovery of new elements.
There is no doubt that the term "scientific theory" is misused since it does not explain whether or not the theory has little or a lot of evidence, the theory of evolution for example has endorsed years of experimental conformation before gaining acceptance by the scientific community. Clearly the vulnerability does not weaken a theory but rather strengthens it by proposing thorough reasoning that may lead to possible laws and discoveries. I believe that both laws and theories play a vital role in shaping the way we perceive aspects in the natural sciences because of the way it allows one to jump to conclusions that may lead to successful future discoveries.
