FutureisNow said:Fred, I think you're missing the point that natural selection is still operating. (...)
Am I? Maybe, but where is the environmental pressure?
What I observe is that:
- Everyone gets kids and social benefits with it.
- Kids mortality is at historic lows.
- Survival till mating age at historic highs.
Income? Level of development?
- I do not think there is a positive correlation between income and progeny. (if there is a correlation, it could well be negative)
- There is a negative correlation between electricity consumption (level of development) and the number of kids.
Time frame?
A genetic advantage needs time to spread... Say 60 generations ago (that takes us back to year 1 of our accounting system), you and your wife have a genetic advantage and are perfectly adapted to your food and environment... You ride a donkey, eat gruel, have good teeth and are resistant to the Flu, Plague, smallpox, athlete's foot and tetanos!
What good does that do your descendants who drive Ferraris, visit the dentist, eat pizza, are vaccinated, powder their feet and use antibiotics?
Without even looking at the environment (food, etc...) that has probably changed once per century (every 3 generations) since, every advantage you may have had 2000 years ago, is flattened out.
Very possibly I am missing something, but I don't know what it could be... maybe you can help me see what you see?
