Detailed explanation-1: -Evidence in the form of the fossil record, geological formations, and genetics attest to change having taken place and give clues to how evolution works. The theory of evolution puts these clues together into a cohesive explanation of the diversity of living things.
Detailed explanation-2: -Fossil remains have been found in rocks of all ages. Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms in the newest rocks. This supports Darwin’s theory of evolution, which states that simple life forms gradually evolved into more complex ones.
Detailed explanation-3: -common ancestor: The most recent ancestral form or species from which two different species evolved.
Detailed explanation-4: -Darwin defined evolution as “descent with modification, ” the idea that species change over time, give rise to new species, and share a common ancestor.
