Please help in my PoE.

Conclusion: It was human migration and not climatic change that precipitated (caused) the extinctions of large animal species.

(y)humans moved from one place to another because of climate changes (more specifically climate becoming warmer) but animals stayed at that place only and became extinct because of climate warming (my assumption)

The main question stem, though takes a different stance. It says :
It was human migrations and not climate warming that caused extinctions

I need an answer choice that makes above conclusion more believable.

Quote:
(A) Many animal species, such as deer and bison, continued to thrive in Europe even after humans migrated there.

I need to LINK human migrations with extinctions, not beak the link.
This if at all weaken the conclusion.

Quote:
(B) Several periods of marked climatic warming have occurred in Europe, during which many large animal species that lived there became extinct.

This makes me think climate warming caused extinctions of animal species, not human migrations. I am looking for other way round.

Quote:
(C) Many animal species that became extinct in Europe survived longer in areas that were isolated from human populations but that experienced intense climatic warming.

Here first THAT refers to animal species and second and third THAT refer to AREAS. Now I am linking areas in which animals lived to both climate warming and human isolation. How can this strengthen my argument?

Quote:
(D) In some areas of Europe, only a few archaeological sites have yielded evidence that shows an overlap between the arrival of humans and the extinction of large animals
.
ONLY word catches my eye and makes this choice incorrect.

Quote:
(E) Some large animals had become extinct in Europe even before humans migrated there.

Nope, this breaks the connection between extinction and humans migration.
Incorrect.

Quote:

First of all, (D) is only talking about SOME areas of Europe. Regardless, (D) only tells us that there is some evidence of an OVERLAP. We already know from the passage that there was an overlap. We need evidence that human migration CAUSED the extinctions. (D) doesn't help us.

Quote:
(C) Many animal species that became extinct in Europe survived longer in areas that were isolated from human populations but that experienced intense climatic warming.

Let's compare two areas in Europe:

  • Area A experienced climatic warming and the arrival of humans.
  • Area B experienced climatic warming but NO arrival of humans (i.e. Area B was isolated from human populations).

Both areas had large animal species. Choice (C) tells us that many of the animals that became extinct in places like Area A survived LONGER in places like Area B. Both areas had climatic warming, but only Area A had humans. This evidence suggests that it was the humans, not the climatic warming, that caused the extinctions.
