Here’s Why People Are Getting Smarter And Taller

Well hi there! Glad you could make it today. Coffee’s perked and there’s a tray of indescribably delicious virtual treats awaiting your pleasure so help yourself. Here’s an interesting summary to get you thinking...

Data from 350,000 people in over 100 different studies shows people are getting smarter — and this is why…

The more genetically diverse your parents are, the more likely you are to think quickly, a new study finds. 

People whose parents are genetically dissimilar are also more likely to be taller.

The data comes from 350,000 people in over 100 different studies.

Researchers from the University of Edinburgh looked at similarities in the genetic code of people’s parents.

When parents share the same genetic code, this is a clue that they are (distantly) related. (Aha! The family that plays together stays together!)

Greater genetic differences, though, indicate that people’s parents are more likely to be unrelated.

Over time genetic diversity seems to be favouring people who are taller and think faster.

Dr Peter Joshi, of the University of Edinburgh’s Usher Institute, said:

“Our research answers questions first posed by Darwin as to the benefits of genetic diversity. Our next step will be to hone in on the specific parts of the genome that most benefit from diversity.”

Dr Jim Wilson, at the same institution, said:

“This study highlights the power of large-scale genetic analyses to uncover fundamental information about our evolutionary history.”

The study is published in the journal Nature (Joshi et al., 2015).

Very interesting...

See ya, eh!
