Cue the Counterblast
Piece in the Telegraph today saying we are evolving to have more children later in life. To help us stay fertile longer we will be less troubled by diseases such as type 2 diabetes, heart problems and obesity that occur in middle age and beyond.
Professor John Hawks, the anthropologist who led the team of scientists behind the research, told the paper that genes allowing us to stay fertile for longer, as we delay having children, seem more important than living longer in itself.
"The trend has been towards later reproduction," Hawks told the Telegraph. "Many people wait to have kids until they are in their late 30s to 40s. But very few people lived in their 40s more than 50,000 years ago. That's a big biological change. So genes that impede fertility at later ages must be experiencing stronger and stronger selection pressure."
Hawks continued: "The bottom line: people are unlikely to live much longer in the future - at least, due to genetic changes - but they are likely to be better at having kids older."
Music to my ears.
