Final answer:
Human activity, including hunting and habitat modification, has caused the extinction of large animals and has had a significant impact on the diversity of species.
Step-by-step explanation:
Humans have had a significant impact on other species for thousands of years. An example of this is seen in the extinction of large animals. Early human hunters killed many large mammals and marsupials, leading to the disappearance of species such as mammoths, saber-toothed cats, giant sloths, and giant marsupials like diprotodons and zygomaturus. Human activity, including hunting and habitat modification, has caused these extinctions and has had a profound impact on the diversity of species.
