Natural Selection

White Peppered Moth
look at this he has six fingers right that is caused by natural selection
Black Peppered Moth
Charles Darwin discovered the natural selection found it out by studying the effects of crossbreeding and inbreeding in plants and animals am I right am I right am I right. Natural variation occurs among the individuals of any population of organisms. like some peacocks are albino and some aren't but the albino ones don't have children because the most colorful one have children so they can't reproduce the girls only like the most colorful one, Charles Darwin wrote a book about natural selection, when he was young he study about tortoise, worms, barnacles, fish, fossils, insects, birds, rocks and even his own family he studied a lot of stuff he studied so many things I'm right am I right am I right, can you see the person with six fingers it is a disease you can get when you are born and sometimes some people have six toes when you are born you can be albino you know you become all white did you know that if you are albino your eyes are red because your eyes don't have any color on your eyes so it is red because that is your blood because your eyes are really clear that's why it is red, there are a lot of problems but normally you only have one problem, the peppered moth looked like a moth that was white with black spots and it looked like a tree but some where black and some not all got eaten but when the factories came the trees became black so the black ones lived but now the trees are becoming normal again so now the white ones are living again and the factories might turn the trees black again so it might happen again, the peppered moth really looks like a tree look at the pictures and see. Natural variation occurs among the individuals of any population of living organisms, chosen by natural selection are eye color like some eye color are different like some people have blue eyes and some people have green eyes and some people have brown eyes and some people have black eyes and some people have light blue and some people have light green and some people have Chartreuse green and some people have Hazel like me and your eye color becomes darker each day a little bit darker like my dad's eyes were blue when he was born but now his eyes are every dark green any way  some people have grey eyes, your eyes might be your grandfather's or you dad's or mom's or your grandmother's or a mix of any of them like a mix of your mom's and dad's or a mix your grandmother's or grandfather's. Charles Darwin was married to Emma Wedgwood who was actually his cousin, Giraffes have medium necks to reach the leafs but all ones with short necks died because they could not reach the leafs with they're necks and the tall neck ones were too high so they could not reach the leafs because it was too tall, babies with that are small are too weak so they will die of a sickness, big babies are strong but will die because it's too big to come out of the mom and a medium is the best of all because it's strong and can come out of the tummy, some of the grey wolves are domesticated animals like the greyhound and corgi also they could have children but they would look really weird because it will become a weird hybrid because it is a different type of breed and it will make a hybrid.In 1859, Charles Darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation.The idea of natural selection predates the understanding of genetics. Mutation was caused by natural selection. When the environment gets dirtier darker moths will get eaten less often their for they will have more time making baby moths, while the white ones get eaten more so the black moths will get more common. Natural selection is when your genotype changes. The peppered moth survived because their was a variation of species which was heritable and every moth that had that trait survives the most. In 1870 Darwin wrote to his neighbor parliamentarian John Lubbock requesting a question be added to England's census regarding the frequency of cousins marrying and the health of their offspring. Darwin studied the effects of inbreeding in plants and animals; their descendants would be weaker and sick and the same with Darwin's family. Emma and Charles had 10 children, their children were not very robust, some of their children could not have kids of their own.
