GoKawiilStudy links ant diversification to asteroid that ended dinosaur era
Researchers studying ant genomes report that the group's rapid diversification into roughly 15,000 known species accelerated around 66 million years ago, coinciding with the mass extinction event caused by an asteroid impact. The scientists attribute part of this genetic diversification to bursts of transposable elements, sometimes called 'jumping genes,' which resemble retroviruses in behavior.
GoKawiil's interpretation of the reporting above, not reported fact.
The findings suggest that mass extinction events can reshape evolution not just by clearing ecological space for survivors, but potentially by triggering genomic changes that accelerate diversification. This could offer researchers a new way to understand how catastrophic events leave lasting marks on the genetic architecture of surviving lineages, beyond simple opportunity and competition.
- Ants' genetic diversification intensified roughly 66 million years ago, aligning with the asteroid-driven extinction event.
- Transposable 'jumping genes' are identified as a likely contributor to this burst of diversification.
- The research implies mass extinctions may influence evolution at the genomic level, not just through ecological opportunity.
