Ascientist finds hominid fossils in china and in australia. judging by the rock layers in which both the fossils were found, the scientist suspects that they are approximately the same age. what should the scientist do next to build a stronger case that the fossils are the same age?

Through Carbon dating , exact age can be determined

Explanation:

The samples of the two fossils must be derived and their age must be derived through the process of carbon dating.  

Carbon dating is a scientific process through which exact age of fossils can be estimated based on the amount of radioactive carbon left within them.  

The age of the sample from the two fossils can be determined by examining the amount of carbon-14 (radioactive carbon) present in them and then doing a back calculation to determine the age of fossil based on the atomic number of radioactive carbons and its half-life period.  

it should be d) transitional fossils.

they show the gradualism of evolution throughout a period of time
