Did the thylacine start naturally or did humans interbreed it?

The thylacine, also known as the Tasmanian tiger, did not result from interbreeding with humans. It was a distinct species that evolved naturally in Australia and Tasmania.

Here's why:

* Different lineages: Humans and thylacines belong to entirely different branches of the tree of life. Humans are primates, while thylacines were marsupials, mammals that raise their young in pouches.

* Geographic separation: Humans arrived in Australia around 65,000 years ago, while the thylacine lineage diverged from other marsupials millions of years prior.

* No evidence of interbreeding: There is no scientific evidence to suggest that humans and thylacines ever interbred.

The thylacine's extinction was primarily attributed to habitat loss, hunting, and disease, not interbreeding with humans.
