According to the theory of evolution, amphibians evolved from ancient fish. which of these would best validate the theory? a. record of history of a place b. a study published by a research scholar c. record of temperature changes of a place b. a study crediting the theory by many scientists

B. a study crediting the theory by many scientists

Explanation:

A theory becomes a scientific law when it is repeatedly tested by several scientists around the world and same results are found by each of them and therefore, no point of conflict is left.

Similarly, the best way to validate a theory is by conducting the same study at different places. If several scientists credit the theory, it means that they have done enough investigation and research and found the theory appropriate.

Therefore, D is the best option.

Hope it help!

wait any answer choices plz

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
