Note changes are in populations not individual organisms.
Another point is that this change does not occur by random chance. Natural selection is the opposite of random chance. It is driven by a survival and reproductive advantage. Mutations are random but they are driven by a non-random process called natural selection. But the vast majority of these genetic mistakes are either neutral or harmful. Only about 0.01% are beneficial, meaning 99.99% of all mutations are neutral or harmful.
Any variation that makes an organism more “fit” for survival is more likely to spread in the gene pool through through this process. A better fit organism does not mean that bigger, faster, or stronger individuals are favored. Only individuals that have a better chance for survival and reproduction are favored. Ultimately, evolution is not goal oriented or a linear process towards some kind of “progress.” It is simply about fitting best in one’s environment, and having the opportunity to reproduce.
Some organisms may not change over long periods of time. Take the example of the American Alligator. It has stayed largely the same for 8 million years because it has little environmental pressure.
Humans are not the most successful species on the planet. Our planet is dominated by single celled organisms. There are 10^30 single celled organisms weighing 10^14 kg. The weight of all humans is 10^11 kg.
What about the idea that evolution is only a theory? In science, a theory means that it is “a model capable of being tested by experiment or observation, and able to predict future observations of the same kind.” It is based on a careful and rational examination of the facts.
Evolution does not explain how life first started. This is called abiogenesis, and it is not well understood like evolution is.
If we evolved from monkeys, why are there still monkeys? We did not evolve from monkeys. Evolution shows that we share a common ancestor that lived probably around 10 million years ago. This ancestor was not a chimpanzee or gorilla, but just a common ancestor to all modern apes, including us. In fact, if you go back far enough, all living things on earth have a common ancestor.
Astronomer Chandra Wickramsinge famously said,“The chances that life just occurred are about as unlikely as a typhoon blowing through a junkyard and constructing a Boeing 747,”– This is incorrect.A better analogy would be this: Start with a million junkyards, put a tornado through each. Exhaustively test the wreckage left after each one to find the most flight worthy object. Make a million exact copies of that most flight worthy combination of junk yard and object. Put another million tornadoes through it, run exhaustive test. Make a million more copies of the junkyard and most flight worthy object. And keep doing this over and over millions of times, until you produce some kind of machine that can fly. Then make millions of copies of that, and further refine for flight worthiness, and keep doing this over and over for millions of years. You will end up with something that might be even more flight worthy than a Boeing 747 - if the evolutionary driver is flight-worthiness.
The idea of entropy applies to closed systems. The earth is NOT a closed system. The sun is spraying it with huge amounts of energy every day. Overall entropy is increasing of the closed system that contains earth and the sun, but this does not mean that pockets of lowering entropy cannot exist. Your refrigerator is making the food inside cooler, and decreasing the entropy of the food inside, but the entropy of your whole house if it was a closed system would be increasing. #evolution To understand evolution, you need to appreciate that quadrillion-to-one chances happen. While mutation is random, which mutations survive is not random. Given enough time, the accumulation of one beneficial mutation after another can produce amazingly complex systems. There is not a single piece of credible evidence to disprove Evolution. There is really not much in science that is as well proven.\n
