If a species needs to continue its lineage, one of the foremost criteria is to maintain a healthy number of population. There were many species that existed before humans, and most of them thrived up until they were hunted to extinction.
One of the most prominent records of a species going extinct because of humans was the moa – a large flightless bird that was endemic to New Zealand. Before humans hunted them to extinction, their only predator was the Haast’s eagle, one of the largest species of eagles to have ever existed.
