Pleistocene megafaunal die-offs are often attributed to human overhunting, with some researchers arguing that expanding hunter populations drove rapid collapses in large-animal numbers. Yet radiocarbon series and ancient-DNA reconstructions show no surges in human population or site density that coincide with key extinction pulses—when the first regional losses appear, when multiple lineages decline simultaneously, or when disappearances peak, suggesting that ______

Which choice most logically completes the text?

Ahunting pressure from early humans affected different megafaunal lineages in markedly different ways.

Bmajor extinction waves did not depend on contemporaneous increases in human population density.

Chuman populations were smallest during the intervals when the largest megafaunal losses occurred.

Dmegafauna would have declined even more rapidly if human groups had been slightly more numerous.
