What evolutionary concept explains Thylacoleo's feline appearance despite being unrelated to cats?
Answer
Convergent evolution
The striking similarity in appearance and ecological role between Thylacoleo and placental big cats arises because both groups evolved similar traits independently to thrive in similar ecological niches. This process is known as convergent evolution. Thylacoleo developed features optimized for hunting large prey while evolving in isolation on the Australian continent, resulting in physical characteristics—such as powerful build and predatory adaptations—that overlapped significantly with the niche filled by lions or leopards elsewhere. This independent development of similar solutions to similar environmental challenges is the definition of convergence.
