Refer to the figure.

- Large-scale community changes observed historically took thousands of years. For example, it took from 18,000 years ago to 6,000 years ago for forest tundra to reach even a portion of its current geographical location. Which factor will increase the susceptibility of species to extinction due to our current, rapidly changing environment that was not present historically?
A) Assisted migration by humans
B) Habitat fragmentation
C) Development of novel communities
D) Accelerated evolutionary changes

Quizplus · Accepted Answer

Habitat fragmentation is a modern phenomenon caused by human activities that isolates populations, making it difficult for species to migrate or adapt to rapid environmental changes, increasing their risk of extinction.
