Question

Scientists uncovered a fossil of a newly discovered species of raptors (predatory birds). They hypothesized that the raptors branched off from larger, flightless raptors about 60 million years ago. Which of these resources did the scientists most likely rely on to form their hypothesis?

A. Fossil records
B. Genetic testing
C. Ancient texts
D. Eyewitness accounts

Answer 1

Scientists most likely relied on fossil records to form their hypothesis that the newly discovered species of raptors branched off from larger, flightless raptors about 60 million years ago.

Step-by-step explanation:

The scientists most likely relied on fossil records to form their hypothesis. Fossil evidence can provide valuable information about the existence of different species and their characteristics in the past. By studying the fossils of the newly discovered species of raptors and comparing them to the fossils of larger, flightless raptors, scientists can make informed inferences about the evolutionary history and branching off of these predatory birds.
