Final answer:
Two populations of hyenas being different subspecies means they have distinct genetic differences that have accumulated over time. These differences could be due to a variety of factors such as geographic isolation, different ecological pressures, or genetic drift.
Step-by-step explanation:
In biology, two populations of hyenas being different subspecies means they have distinct genetic differences that have accumulated over time. These differences could be due to a variety of factors such as geographic isolation, different ecological pressures, or genetic drift. As a result, the two populations may have different physical characteristics, behaviors, or adaptations to their respective environments.
For example, let's say one population of hyenas is found in the grasslands of Africa and the other in the forests of Asia. The African population may have adaptations for hunting in open spaces, while the Asian population may have adaptations for navigating through dense foliage.
The distinction between subspecies allows scientists to classify and study the diversity within a species. It also highlights the importance of geographic isolation and genetic variation in driving the evolution of different populations of organisms.
