Question

Carbon isotope signatures present in fossil teeth can provide insight into the diet of fossil human ancestors.

a. True
b. False

Answer 1

Fossil teeth can provide insight into the diet of fossil human ancestors using carbon isotope signatures.

Step-by-step explanation:

True

Fossil teeth can provide insight into the diet of fossil human ancestors through carbon isotope signatures. Carbon isotope analysis can determine the proportions of different carbon isotopes, such as Carbon-12 and Carbon-13, in fossil teeth. Different types of food sources, such as plants or animals, have distinct carbon isotope signatures. By comparing the carbon isotope signatures of fossil teeth with those of known modern organisms, scientists can infer the diets of fossil human ancestors.
