Detailed explanation-1: -Absolute Dating The nuclear decay of radioactive isotopes is a process that behaves in a clock-like fashion and is thus a useful tool for determining the absolute age of rocks. Radioactive decay is the process by which a “parent” isotope changes into a “daughter” isotope.
Detailed explanation-2: -Evidence that land vertebrates descended from fish includes transitional fossils, anatomical similarities among embryos and adult animals, and genetic evidence of common ancestry.
Detailed explanation-3: -Fossil records show evidence of how living organisms have evolved or changed over time. Paleontologists were able to detect the particular order in which these organisms have lived. For instance, simpler organisms inhabited older rocks and complex organisms were found in younger rocks.
Detailed explanation-4: -One pattern in the fossil record is the presence of forms with transitional characteristics, arranged in sequential stratigraphic order. This means that the fossil record provides evidence for evolution and it shows tiny changes in the structures of organisms as time moved forward.
