Question

There is only one piece of evidence that supports the mammal competition hypothesis. After viewing the details of this evidence and its relation to the mammal competition hypothesis, do you think this is a widely accepted conclusion in the scientific community? Explain your answer.

Answer 1

An evidence for the mammal competition hypothesis are the fossil records.

A gradual decline in the number of dinosaur species would likely mirror an equally gradual cause of their ultimate extinction. Conversely, a sudden "now you see them, now you don't" end to the dinosaurs implies a catastrophic cause. Depending on location and interpretation, the fossil record seems to say different things.

While mammals certainly prospered on the heels of the dinosaur extinction, it is unclear whether mammals and dinosaurs experienced little competition or if they regularly challenged each other for limited resources.
