Capybara
Individual capybaras achieve lifespans of 8-12 years in the wild, extending to 12-15 years under protected conditions. This modest individual durability belies the species' remarkable evolutionary persistence. The capybara lineage extends back approximately 8 million years, with the genus maintaining its essential characteristics throughout this period.
The species has demonstrated exceptional adaptability to environmental change. Capybaras have successfully colonised urban environments in parts of South America, appearing in parks, golf courses, and residential areas with characteristic indifference to human proximity. Their semi-aquatic adaptations provide resilience against both terrestrial and aquatic predation pressures.
Furthermore, the capybara's reproductive efficiency ensures population stability. Females produce litters of 4-8 offspring annually, with minimal parental investment required beyond initial nursing. The species approaches what ecologists term sustainable abundance.
