Excellent Evolution

     Charles Darwin had thought about the theory of evolution. Animals and plants of the same kind are said to belong to a particular species. For example, dogs belong to one species, human beings to a different species, and White pine trees belong to a different family or species. The bones or imprint of plants/animals are evidence that these species lived long ago and have changed over periods of time. This evidence is called fossils.

 Dinosaurs lived here for more than 100 million years on our Earth. 65 million years ago the last dinosaur died and they became extinct, meaning there was no more of them on Earth. Dinosaurs had not always lived on Earth , just like people,roses, and termites. The fossil evidence proves that species change or evolve over time. Species changing over time is called evolution.

Naturalists Charles Darwin and Alfred Russell Wallace are credited with the theory of evolution, which has united biology, the study of living things. 

     Here are some of the major ideas that Mr. Darwin had.The individuals making up a population, whether it is a human population, a population of squirrels, or a population of birch trees are not exactly alike. The human population, for example there are different races and some individuals that are better able to fight diseases than others. Some have better eye sight than others. Differences are called "variation." Some differences, such as the ability to fight off some diseases, are helpful and may be passed on to the next generation. The result of such naturally favored people producing more children than unhealthy people do, is an increased number of healthy people in the following family. So nature selects those people of any population who are fittest and against those individuals who are less fit. That is what is meant by the expression             "Survival of the fittest." This way each new generation is a tiny bit different from the previous ones. Those differences from one generation to the next, can cause one species to change, or evolve to better survive in its environment.
