6 -- Natural Selection Made Easy

Explains natural selection in simple terms. A must for anyone who is confused by the Theory of Evolution, and wonders why it's taught in classrooms. This video is part of the 'Made Easy' series that explains the history of our world, from the Big Bang to the human migration out of Africa.

> why arent there any other THIRD level of intelligence on earth. its eather animal or human.

Not true. Not even remotely. You have bacteria and plants, with less intelligence than animals, you have stupid animals like earthworms and goldfish, you have smarter animals like cats and dogs, then crows and octopi, dolphins and apes, and humans. Humans ARE animals. Drawing the line as you have is like saying there's only two heights on earth, either giraffe or animal.

"The video pretends that Long-Necked parents give birth to long-necked children. This is not so."

Long-necked parents will give birth to long-necked children if the gene for long necks is dominant or the parents are homozygous. That however is not the point the video is making. Genes which perform well in the environment will become more common in the gene pool as genes that perform worse get their owners killed.

"2. A group of long-necked and short necked animlas that live together and mate together will have both long-necked and short necked children."

That's Mendelian genetics, and it applies if the length of neck is determined by single genes. If it isn't, such as with skin tone, you can have a range of colors by inheriting only the light or only the dark genes from your parents who have a mixture.

"1. We don't see this variation thingy happening."

Yes we do. Butterflies have subtly different patterns. Your children do not look exactly like each other. And also all breeds of dog.

"People have been people for as long as we know."

And humans will continue to be humans, just as they are still apes, monkeys, mammals, vertebrates, animals, and eukaryotes.

@MrPeterpott "2. A group of long-necked and short necked animlas that live together and mate together will have both long-necked and short necked children" Yes, and the short-necked ones are less likely to survive to an age where they can reproduce in an environment where having a longer neck is an advantage. Hence the allele frequency in the population will change in favour of the long-necks. That's called evolution.

@MrPeterpott "1. We don't see this variation thingy happening. People have been people for as long as we know." Yes, you're right there. Every single person on the planet is exactly the same. Indistinguishable. I keep committing adultery inadvertently due to the fact that my wife is identical to every other female human. Well said. Maybe.

[MrPeterpott]

There are many problems with this. 1. We don't see this variation thingy happening. People have been people for as long as we know. 2. A group of long-necked and short necked animlas that live together and mate together will have both long-necked and short necked children. The video pretends that Long-Necked parents give birth to long-necked children. This is not so. Of course the video presenter is slick and glosses over details that ruin his fantasy.

How could anyone disagree with this?

I killed a six pack about 15 minutes ago, and this is still crystal clear.
