Some major flaws here....
1) There is no "Cancer gene"... there are alleles of particular genes that can make you more prone to develop cancer as you age. 2) Cancer isn't just genetic... you have alleles that make you more prone to get cancer, but that doesn't mean that you have a 100% chance of developing cancer. now about mistakes about Natural Selection.... 1) Natural Selection doesn't mean that "bad genes" get removed from the population... it means that genes that prevent an individual from surviving long enough to reproduce are rare in the population. 2) "Bad genes" is mistaken idea anyway as many genes that may be dangerous in some situations are beneficial in others... for example Sickle Cell gene. 3) Natural Selection doesn't mean that eventually living things become perfect... it means that over time they change to adapt to their situation. The best examples of Natural Selection in humans are the spread of the Lactose tolerance alleles and the spread of the Blue Eyes allele. All of these started with a single individual and have spread through the population due to their different selective advantages and characteristics. But there are lot's of other examples in humans. So, no... just saying "cancer is bad therefore natural selection is wrong" doesn't work. wa:do

It also needs to be explained why human brains have shrunken in the last 20,000 years by nearly 20%. Natural selection is it? Really? And it's also natural selection that human beings are getting smaller according to scientific statistics? Natural selection is a social and political theory, it was used so people thought things were getting better. The theory is shot down by all available evidence. |

Because they don't hinder reproduction...duh...

Have you ever actually read a book on the subject?

I dont think he has a high school education on the subject, if he does I would think he failed

Diabetes, Heart Disease and Cancer and so on are a result of our new living situation and will take a long time to sort out. The good news is we already are seeing beneficial alleles granting resistance to those diseases apparing in the population and they are starting to spread. Natural Selection at work. Quote:
But then, you don't see anyone dying of the Spanish Influenza today either... nor are they likely to drop dead of the "Black Death" almost instantly. Quote:
But brain size isn't everything, smaller brains are actually better at not killing mothers as our pelvis isn't getting any bigger. Plus, have I mentioned the effect that environmental pollutants can play? Tar Shrank Heads of Prehistoric Californians Over Time? Quote:

If accident dropped radioactive waste or some kind of chemical on 2000 people, the generations of those people would still have it, infact the bad traits would continue to be common, "natural selection" would not get rid of those traits, go and speak to some of the successive generations of the WW2 soldiers or Vietnam whos ancestors spent time working with chemicals or were hit by bombs or gases, this natural selection is a fairytale.
