Answer
While high genetic diversity can contribute to the survival of a species by providing a genetic pool that can adapt to changes, it is not a direct cause of extinction.
Step 2
B. its disc-shaped mouth was unsuitable for ingesting prey.

Answer
This option may suggest a physical limitation, but it doesn't account for the other factors that could lead to extinction.

Answer
This may aid in survival, but does not explain extinction. If the conditions changed drastically, even well-adapted offspring could fail to survive.
Step 4
D. selection pressures changed dramatically due to rapid climate change.

Answer
This is the most plausible explanation for extinction. Rapid climate change can alter habitats, disrupt food sources, and impose new challenges that a species may not be able to adapt to quickly enough.
