What is the primary cause of species extinction in the last 500 years?

Human activities such as habitat destruction, pollution, and over-exploitation have caused a rapid increase in species extinction rates. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.

Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept.

Which extinct species is linked to human hunting and invasive species on islands?

“Dodo” for which extinct species is linked to human hunting and invasive species on islands. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. At equilibrium, species identities can continue to turn over even when richness is approximately stable. The model predicts a balance of rates, not an absence of colonization or extinction. The remaining alternatives—“Moa”, “Pyrenean Ibex”, “Passenger Pigeon”—refer to different states, processes, or scales and therefore do not express the same causal relation
