The problem with Orreries—and the theories of the cosmos that prevailed at the time—was that they had to gradually become complex as more was known. These preserved remains offer scientists the rare opportunity to study the skin, hair, and organs of old creatures. Scientists collected DNA from these remains and compared the DNA sequences to those of modern creatures. Describe the link between evolution and the appearance of homologous structures „These may be different types of fossils,“ says another. Synthesizing the contributions of fossil heritage to our understanding of evolution The set of discovered and undeased fossils and their placement in fossil rock formations (fossils) and sedimentary layers (layers) are called fossils. The fossil stockpile was one of the first sources of data that presided over the study of evolution and remains relevant to the history of life on Earth. . . .
