Proof For Evolution Evolution‚ ever since its introduction by James Hutton in the early 1700s‚ has been a very controversial topic with many people opposing the various theories presented by scientists throughout the years. In modern science‚ evolution has come to be accepted by many scientists around the world‚ with significant amounts of evidence from various fields of science provided to support Charles Darwin’s theory of naturally selective evolution - “survival of the fittest” and adaptation

In the 1800s an Austrian Monk‚ Gregor Mendel started to experiment with peas. 1. Genes combined to produce a better end result. 2. Genetically modified were first introduced in Canada in 1990s. B.

Andrew Day Bio Extra Credit Two weeks before Charles Darwin died he wrote a short paper about a clam clamped to a water beetle in a pond in the English Midlands. The man’s son that sent him the beetle worked together with his son and discovered that what Darwin said about evolution was correct. The vindication came from a book that said every organism has a certain chemical code called DNA. Darwin surmised that all Galapagos finches were close cousins and he explained this in his book

Charles Darwin and his Impact on Science Charles Darwin was a scientist‚ specifically a naturalist‚ in the mid to late 1800’s. He proposed many theories to the world of natural science that were later proven to be laws‚ which shows that he had a huge impact on the science world. His two most important advances were the Theory of Evolution and the Theory of Natural Selection. He also studied the importance of Genetics. Darwin’s ideas have also had issues with religions‚ but they have still been proven

The contributions of several doctors‚ researchers‚ and scientists helped improve the health of the growing population. In 1850 the average life expectancy was 42 years. By 1910 the average life expectancy had risen to nearly 55 years. Between 1850 and 1910 there were several advances in the medical field. The introduction of genes‚ white blood cells‚ blood groups‚ insulin‚ rubber gloves‚ aspirin‚ and vitamins and the discoveries of Pasteur‚ Charcot‚ Halsted‚ Zirm‚ Lister‚ and Koch were the starting
