Given below are two statements.

Statement I: All the existing life forms share similarities and share common ancestors. 

Statement II: The geological history of earth does not correlate with the biological history of earth. 

In the light of the above statements, choose the most appropriate answer from the options given below. 

Statement I is true, but statement II is false.

Statement I: All the existing life forms share similarities and share common ancestors. This statement is in line with the theory of evolution by common descent, which posits that all living organisms on Earth share a common ancestry. According to this theory, different species have evolved over time from a common ancestral population through a process of descent with modification. Evidence for this includes similarities in genetic code, anatomical features, and the fossil record.

Statement II: The geological history of earth correlates with the biological history of earth. The correlation between Earth's geological history and its biological history is supported by stratigraphic methods used in paleontology. Fossils found in specific rock layers (strata) help estimate the relative ages of organisms, while absolute dating methods provide precise numerical age estimates. By comparing the ages of fossils from different locations, scientists can establish the timing of evolutionary events, demonstrating how Earth's geological processes have influenced the evolution and distribution of life over time.
