Question
Carbon-14 dating works for fossils up to about 75,000 years old;
fossils older than that contain too little 14C to be detected. Most
dinosaurs went extinct 65.5 million years ago. (a) Can 14C be used
to date dinosaur bones? Explain. (b) Radioactive uranium-235 has
a half-life of 704 million years. If it was incorporated into dinosaur
bones, could it be used to date the dinosaur fossils? Explain

- A construction project required digging hundreds of feet into the ground, which exposed many discrete strata. After a thorough investigation, paleontologists do not find fossils of Tiktaalik or any similar species. Explain why this finding could not be used to refute the theory of evolution.arrow_forward3:10 1 Back Pulse Question 42 (Mandatory) Amphibians evolved directly from which ancestral organisms? a) Small mammals b) Echinoderms (sea urchins) c) Marine invertebrates d) Fishes e) Reptiles Question 43 (Mandatory) Which best explains how Australia has distinctive organisms, such as marsupials, that cannot be found anywhere else on earth? a) Australia experienced a significantly slower rate of evolutionary change. b) Australia was separated and isolated from other land masses for a long period of time. c) There are fewer species of organisms in Australia than most continents. Australia has an unusual climate that has triggered natural selection. e) The predators of marsupials eliminate populations in other locations.arrow_forwardAccording to "Our Earliest Ancestors", why can’t scientists just do DNA analysis on these fossil hominins to determine if they are a separate species and possibly what species they belong to? A.The fossils would need to be in a -5 degree Celsius environment to prevent DNA from degrading B.The DNA of fossil hominins is too similar to modern humans, making it difficult to distinguish between them. C.Scientists can't perform DNA analysis on fossil hominins because the fossils have been contaminated with modern human DNA over the years, making it impossible to isolate the ancient genetic material. D.The technology for extracting DNA from fossils hasn't been developed yetarrow_forward
- Which statement is NOT true about the early hominins: A) The angle of the foramen magnum on Sahelanthropus tchadensis ("Toumai") indicates a vertically oriented upper neck, a clear sign of bipedalism. B) The reconstructed skeleton of Ardipithecus ramidus ("Ardi") suggests she was adapted for bipedal walking and climbing in trees. C) Early hominins such as Sahelanthropus and Ardipithecus had small, chimp-sized brain. D) All of the above are true.arrow_forwardCat DNA is much more similar to dog DNA than to tortoise DNA. Why? (a) Cats and dogs are both carnivores and take in similar nutrients. (b) Cats and dogs have lived together with humans for a long period of time, so they have grown more similar. (c) Cats and dogs have more offspring during their lifetime than tortoises have, so their DNA changes less rapidly. (d) Cats and dogs have a common ancestor that is more recent than the common ancestor of cats and tortoises.arrow_forwardOrganism A lived from 410 to 60 million years ago. Organism B lived from 200 to 100 million years ago. Which organism will be the better index fossil? (1)arrow_forward

- Because the Laetoli footprints date to 3.6 mya and they are clearly made by a bipedal hominin, it is likely that they were made by Australopithecus afarensis, who appears to have been the only hominin around at that time. True O Falsearrow_forward9) Miller and Urey were able to support the hypothesis that life could have arisen through chemical/physical processes available on Earth 3.5+ billion years ago by heating and cooling CH4, NH3, H2, and H2O. What did they find when they did so? A) Lipids formed in these conditions B) Amino acids formed in these conditions C) Nucleic acids formed in these conditions D) Carbohydrates formed in these conditionsarrow_forwardThese are images of the Taung Child, an Australopithecus africanus fossil discovered in South Africa by Raymond Dart. a) Name two features that would have indicated to Dr. Dart that this fossil was very ape-like.b) Name two features that would have seemed very human-like to Dr. Dart.
