Biological Evidence and the Fossil Record Updated.

Biological Evidence and the Fossil Record Updated.The fossil record shows that two groups of organisms are related, which means they share a -ANSWER. common ancestor What do gradualism and punctuated equilibrium have in common? -ANSWER. They are both explanations of the rate of evolutionary change. What is the most likely reason that horses and mountain goats have hooves? -ANSWER. They have homologous structures because they have a common ancestor. Similarities can be seen among related organisms, which shows what? -ANSWER. common ancestry transitional form examples -ANSWER. Australopithecus is a transitional form between apes and humans. Transitional forms -ANSWER. - shows the evolutionary steps between species. - fossils that show intermediate states between an ancestral species and its evolutionary descendants Which fields of science provide evidence for evolution? -ANSWER. biology, chemistry, and geology Which lists the correct order of evolutionary history? -ANSWER. jellyfish, reptiles, mammals The development of embryos is similar because -ANSWER. they come from a common ancestor Molecular homologies -ANSWER. similarities in the molecular structure that make up organisms Mutations -ANSWER. changes in DNA sequences Fossils -ANSWER. - are the preserved remains or evidence of a species - can be mineralized bone, footprints, or organisms trapped in a sap - Fossil age can be determined The fossil record -ANSWER. depicts evolutionary change over the last 4 billion years and is evidence for evolution because it shows change in species over time
