A first look
This shelf is still being planted — the questions are being written and checked. Come back soon. A Skill needs at least 5 checked questions before it opens here.

Question 2 of 3
Which statement most accurately combines the human‑hunting (overkill) explanation and the rapid‑climate‑change explanation for the loss of Pleistocene megafauna, and correctly cites the type of evidence that supports each hypothesis?
Question 3 of 3
A research team wants to bring back two extinct animals—the Irish elk and the thylacine—using modern genetic techniques. Which statement correctly lists the technical steps they must take and provides one scientifically valid argument supporting de‑extinction and one scientifically valid argument opposing it?
