Evolution and Charles Darwin

Uploaded by myusername on Aug 11, 2001

Charles Robert Darwin has had the greatest influence on the world by proving the evolution of living things. Charles Darwin had first noticed the similarities of plants and animals when he took a five-year cruise on the H.M.S. Beagle, which was available to him through a friend from school. During the cruise Charles Darwin started becoming interested with the similarities between the plants and animals that were similar on different islands with similar climates, so he decided to study them more closely.

With the studies that Charles Darwin obtained he published his first work, “The Origin of Species.” In this book he explained how for millions of years animals, and plants have evolved to better help their existence. Darwin reasoned that these living things had gradually changed over time to help themselves. The changes that he found seemed to have been during the process of reproduction. The traits which would help them survive became a dominant trait, while the weaker traits became recessive. A good example of what Darwin was trying to explain is shown in giraffes. Long-necked giraffes could reach the food on the trees, while the short-necked giraffes couldn’t. Since long necks helped the giraffes eat, short-necked giraffes died off from hunger. Because of this long-necks became a dominant trait in giraffes. This is what Charles Darwin would later call natural selection.

Charles Darwin also showed how new species were created on the acts of evolution. It is easily explained by having big differences from the effect of natural selection, which were considered to be new species. So back in the beginning, before the effects of evolution had occurred there was just one specie, which evolved to make the species that we know today. So somehow all species are somewhat connected. The basis of what Darwin was proving was that life on Earth is simply the result of billions of years of adaptation to the changing environments. That is why certain species can only live in certain climates. This can be explained with the color of your skin, or the growing of plants.

The color of your skin used to depend on where you live. (Before transportation became so easy.) Darker skinned people would live where it is hotter, and the sun shines more. Lighter skinned people would live in cooler, less sunny areas. This is because the darker pigments in your skin would keep you from burning. (Like when you...
