Mary Anning reconstructed the fossil skeletons of many animals new to science. During her studies, she discovered that some species have become extinct.
Which of the following is one main reason a species becomes extinct?
A. overproduction
B. increased variation
C. decreased competition
D. climate change

Hello There. The correct answer is  D. Climate change.

Because it shows that Anning continued to support herself selling fossils. Her primary stock in trade consisted of invertebrate fossils such as ammonite and belemnite shells, which were common in the area and sold for a few shillings. Vertebrate fossils, such as ichthyosaur skeletons, sold for more, but were much rarer.

Hope It Helps! .ω.
