Natural Selection Vs Human Evolution

Where did we come from? As per science shows, we evolve from our ancestors an even though there are facts about it, there is really hard to know since we have been the same humans since millions of years ago. We see evolution in bacteria more rapidly than humans and with the course of years, we see changes. The example of the wisdom tooth, it was to believe that it was used years ago to chew on raw meat or masticate raw vegetable, but now this day we don’t use them so most of the current wisdom tooth come out bad, or some don even come and they have to be removed because the mouth is getting smaller. Use it or lose it as they say. Same with the appendix, today is considered a vast organ but before it served as an organ close to the large

There are different methods of species changes, but the idea comes originally from Natural Selection. The Theory through natural selection was the first scientific theory by Charles Darwin in his book on the Origin of Species. Darwin said that people with traits like to their surroundings who lived long enough to reproduce, pass down those genes to their following generation. If a family had less trait genes, when they die they would not pass on those traits.

Over time, the strongest species would survive. Ultimately, after a period of time, these small variations would sum to create new species. These modifications are made us human. The theory of Evolution states that individuals cannot evolve, we just simply adapt to anything that surrounds us. This changes add up and sooner or later the entire species would have evolved from what it was.

Evolution takes part in everything that is around us. The process of evolution is so slow that a visible trait is not observable until thousands of years have passed, this is a very long time to be a witness in a human lifetime, but thanks to studies we know that we evolve in one way or the other. Some cases show quicker than other, like the reproducing of bacteria. Even though it is a faster change than humans, it still takes a few weeks to months for bacteria to evolve. The more generations exist; the more changes will

A person that studies human evolution has ideas about how environmental conditions affect us. We are one human race, but still, we look different based on place of birth On earth. Climate changes affect the process of evolution, heat, cold dryness all influence is the survival of all spices. In the case of the human skin and other aspects correlate with the geography of the place we live. For people in where there are areas of hotness, they anatomy tend to adapt and to survive in those conditions, the increase of sweat glands, the amount of melanin in their skin to help protect with the UV lights and reducing the amount of hair in the body for the faster cooldown of the body. A significant amount of UV rays penetrates the skin; UV lights help with the synthesis of vitamin D which is needed for calcium in the bones. People in colder areas have lighter skin color, to help with the penetration of UV rays since in cold areas the sun is not so intensive like in
