Final answer:
The extinction of Miss Waldron's red colobus is currently considered false, with unconfirmed sightings raising hope for its existence. The factors contributing to species extinction are complex and multifaceted, including habitat loss, hunting, climate change, and invasive species as possible causes.
Step-by-step explanation:
The statement regarding the extinction of Miss Waldron's red colobus is false. Although it was once thought to be extinct due to factors like habitat loss and overhunting, there have been unconfirmed sightings suggesting it may still exist. In general, when discussing extinctions, it is critical to consider various causes such as climate change, invasive species, zoonotic diseases, and overharvesting. Each of these factors can contribute to the decline of species. For example, research like that of G.M. MacDonald et al., which discusses the pattern of extinction of the woolly mammoth, often points to a combination of human impacts and natural changes in the environment influencing species survival.
