Question

A scientist uses radioactive dating to determine the age of a fossil and discovers that a hominid species may have existed much earlier in history than he thought. Which of the following would most likely increase the reliability of this finding?

Using radioactive dating to determine the age of similarly shaped fossils
Repeated analyses of the fossil finding it to be the same age each time
Using radioactive dating to find the age of fossils found in the same geographic location
Publication of his findings in different paleontology magazines

Answer 1

scientists combine several well-tested techniques to find out the age of fossils. relative dating is when fossils and layers of rock are placed in order from older to younger, and radiometric dating allows the actual ages of certain type of rocks to be calculated.

Answer 2

Repeated analyses of the fossil finding it to be the same age each time
