SUMMARY

The discussion centers on a recent Australian study regarding molar agenesis and ongoing human evolution, particularly highlighted by a BBC report. The study, titled "Recently increased prevalence of the human median artery of the forearm: A microevolutionary change," notes that many babies are now being born without wisdom teeth and that facial structures are evolving, resulting in shorter faces and smaller jaws. The likely explanation for these changes, particularly in Australia, is attributed to gene flow.

PREREQUISITES
  • Understanding of human evolutionary biology
  • Familiarity with genetic concepts such as gene flow
  • Knowledge of dental anatomy and molar agenesis
  • Awareness of contemporary studies in human evolution
NEXT STEPS
  • Research the implications of gene flow on human evolution
  • Explore the relationship between jaw size and dental health
  • Investigate the prevalence of molar agenesis in different populations
  • Study the anatomical variations of the median artery in humans
USEFUL FOR

This discussion is beneficial for evolutionary biologists, dental professionals, anthropologists, and anyone interested in the genetic changes occurring in modern humans.

Whilst driving yesterday I half-heard a headline on BBC radio which appeared to be about a new Australian study on molar agenesis (they did not use that term). Now I can find no reference to this study on the BBC website nor anywhere else - can anyone here shed any light on this?
 
Biology news on Phys.org
Can you give a better description for what the study found?

This is the feature on the BBC's 'Science Focus' website:
https://www.sciencefocus.com/news/humans-are-evolving-an-extra-artery-in-the-arm/

The phrase that pricked up my ears was this: "The median artery is not the only example of ongoing human evolution. Many babies are being born without wisdom teeth. Dr Lucas said faces are becoming a lot shorter, with smaller jaws meaning there is less room for teeth."

The paper that is referenced is Recently increased prevalence of the human median artery of the forearm: A microevolutionary change.

I think there were some more very unscientific comments; it occurs to me that the most likely explanation (for contemporary molar agenesis and changes in lower jaw shape in Australia) is gene flow.

I don't remember the name of the BBC correspondent, it certainly wasn't the (always excellent) Pallab Ghosh.
