Why Are There So Many Beetles

The video explores the diversity and resilience of beetles, highlighting their evolutionary success. Beetles make up 20% of all named animal species, partly due to their relationship with flowering plants during the Cretaceous period. Phylogenetic analysis suggests that beetles diversified alongside these plants, aided by unique digestive enzymes acquired through horizontal gene transfer. These enzymes allowed beetles to exploit new niches. Additionally, beetles' ability to adapt to changing environments and avoid extinction has contributed to their long-term survival. The video emphasizes the importance of studying both beetle diversity and resilience to understand their evolutionary success.
