The regular use of Caesarean sections is having an impact on human evolution, say scientists.
More mothers now need surgery to deliver a baby due to their narrow pelvis size, according to a study.
Researchers estimate cases where the baby cannot fit down the birth canal have increased from 30 in 1,000 in the 1960s to 36 in 1,000 births today.
Historically, these genes would not have been passed from mother to child as both would have died in labour.
Researchers in Austria say the trend is likely to continue, but not to the extent that non-surgical births will become obsolete… Rink ndio hii http://www.bbc.com/news/science-environment-38210837

Quite interesting. The more we advance scientifically, the greater the decline in desirable human traits.

And with CRISPR genome editing, in the near future, maybe we will be able to scientifically determine exactly what kind of traits our children will have or not have. When Science starts to play god, we can only wonder the consequences

Genome editing? Maybe the Black Mirror episode about killing people of inferior genetics wasn’t far fetched.
