Fading control over 'jumping genes' may explain why big dogs age faster

A study suggests that larger dog breeds may age faster due to less control over 'jumping genes.' This finding could explain why bigger mammals generally have shorter lifespans compared to smaller ones, ranging from a couple of years in mice to nearly 200 years in some whales. For more details, refer to the original research report.
