Natural Selection!

Natural Selection occurs when the animals that are more suitable to the environment survive, and the ones that are not don't.

The animals that survive, of course, reproduce, making the species more adapted to the current environment.

Charles Darwin discovered Natural Selection, when he found out that Galapagos Finches on different islands had different beaks, showing that the species of Finches that was more suitable for that Island survived, and the ones that weren't didn't.

The Finches also increased fitness until it was suitable for the island they were on.

Through Natural Selection we got to where we were today.

If an animal gives birth, usually there is a runt of the litter, which normally does not survive because the other young push it out of the way, leaving it to die.

The sentence above is another example of natural selection.

Darwin married his cousin, which made him think about natural selection and if his offspring would be healthy.

Darwin studied crossbreeding and inbreeding.

Darwin had 10 children. 3 of them died in their childhood and the other 7 were not very healthy, which made him think even more about natural selection and inbreeding.

Giraffes adapted to have medium length necks, with the ones with very long necks dying and the ones with very short necks dying.

Medium is best for Natural Selection, but now the big kids also survive because of a Ceasarian Section, where an operation is made to get the large baby out through a cut in the womb, which they pull the big baby out of.

Birds had a hard time seeing common pepper moths until the trees turned black because of the soot, after that, the rarer, black moths survived.

Charles Darwin, maybe one of the most famous scientists, went to the galapagos islands, and you know the rest, I made notes on it.

Charles Darwin was interested in natural selection for his whole life.

The Galapagos Finches were one of the most important things in science.

Emma Wedgewood was the wife of Charles Darwin, and, actually was his first cousin.

Darwin also studied plant crossbreeding.

The survival rate of babies was better for the middle range babies.

There are lots of examples of natural selection.

The animals need to adapt to the environment, food, water, pretty much any essential thing if they want to survive.

Some animals use sexual selection, like deer and peacocks.

Sexual selection is when the stronger male, in this case, the one with the bigger horns and the bigger plumage, gets all the girls.

Natural Selection is one of the most important types of evolutionary change in history.

Populations can have way more offspring if there is an abundance of food, but when that food runs out, most of the young will die, the survivors being the winners of natural selection.

Normally, the survivors of natural selection should have all of the offspring, making all of the babies like them, so they will survive better than the ones who died.

There are lots of causes of natural selection, including a parasite, change in the weather, change in food and lots of other things.

Charles Darwin was obsessed with observing nature.

Charles Darwin went to the galapagos islands on a ship called the Beagle.

There was someone in the Beagle that didn't want to believe charles darwin, he was a very serious christian.

Darwin's family was not as healthy as the average family in the present.

The Coal Powered Factories is the reason that the white peppered moths almost went extinct.

Only 5 percent of the peppered moths were white after a bit of soot covered trees.

Charles Darwin also studied his own family. Awkward, huh?

The Finches that ate hard seeds had thick beaks, the ones that ate insects had skinny, pointed beaks, and finally, the ones that ate cactus fruit had sharp beaks so they could pierce the cactus fruit's skin.

There are lots more finches with a huge variety of beaks.

Darwin wrote to his neighbor about a question about inbreeding.

Darwin's cousin was Emma Wedgewood, and Darwin's mother was also a Wedgewood.

That Wedgewood trait made Darwin's children very weak, as I said before, 3 died in their youth because of a sickness.

Every plant and animal has to go through natural selection if they want to make the most healthy child.

Populations can have way more offspring than food. This happens frequently if we feed the stray animals too much.

If a species separates enough, they can become two new different species. This is called Speciation.

A deer can use it's horns just to look intimidating.

Breeds of dogs are bred through Artificial Selection, which is when the humans choose what dogs should reproduce.

Before, the darker moths were only 5% of the peppered moths, but during the industrial selection.

There are 4 basic principles of natural selection.

If a trait is favorable, it will be passed on to the next generation of the species.

If a war kills a lot of people and there are only a few survivors, that would be another example of natural selection.

Natural Selection can also happen with plague, in a similar way to war.

Jesiah Wedgewood was a person that founded a really good pottery company.
