Textbook Question
Chapter 15.3, Problem 1TC
The fossil history of some kinds of modem organisms, such as sharks and crocodiles, shows that their structure and appearance have changed very little over hundreds of millions of years. Is this lack of change evidence that such organisms have not evolved during that time?

- A number of scientists believe that the Permian extinction was caused by huge volcanic lava flows (from the Siberian traps) that may have caused low oxygen concentrations compared to the high oxygen levels in the Permian. Does this low oxygen level after the Permian extinction make it likely that dinosaurs, especially large ones, did not evolve immediately after the Permian extinction (252 million years ago)? Why or why not?arrow_forwardWhat do you think geologists would find in the rock record as evidence of human life today million years later?

- Fossils show that dinosaurs originated between 200 and 250 million years ago. Would you expect the geographic distribution of early dinosaur fossils to be on multiple continents or on a single continent? Explain. Hint: refer to continental drift in your explanation.arrow_forwardElaine Morgan makes the case that humans may have an aquatic ancestor in recent evolutionary past. Do you agree with Elaine Morgan’s assertion that human evolved in an aquatic environment? Explain.arrow_forwardThe proliferation of the Homo sapiens species has been attributed by scientists to their migration around the African and Eurasian continents between 70,000 and 100,000 years ago. What enabled this constant migration? What resulted from this constant migration?arrow_forward
- What role do the fossils named “Ardi” and “Lucy” play in the reconstruction of human evolutionary history?arrow_forwardBecause of selective forces, the dinosaurs were superbly adapted to their environments. After the dinosaurs became extinct, the small mammals that had been relatively unimportant animals in the background flourished and evolved into many new types, including the line that led to human beings. It is unlikely that these new types would have ever evolved had not the dinosaurs disappeared. If the extinction of the dinosaurs was caused by an extraterrestrial impact, did it matter how well they were adapted to their environment? What does this suggest about the starting cause in the evolutionary success of these new types of mammals?arrow_forwardYou are studying the evolution of species. After performing DNA analysis, he discovers a gene that is conserved from yeast to humans. In which cellular processes is this gene most like to be involved? Could this gene have evolved to confer some of the complex traits that we observe in modern animals, like multicellularity? Briefly explain.arrow_forward
- While the French biologist LaMarck was correct in proposing that evolution does occur, he believed that the long necks of giraffes evolved as generations of giraffes reached for ever higher leaves on the trees. Using these observations, LaMarck proposed the theory that evolution occurs due to the inheritance of characteristics acquired during an organism’s lifetime. From what you know about the scientific method, why is this incorrect?arrow_forwardWhy is animal evolution during the early Cambrian referred to as an “explosion”?arrow_forwardSome genetic studies suggest that the most recent common ancestor of Homo sapiens that lived outside of Africa spread from Africa about 50,000years ago. Compare this date to the dates of the fossil record. Can both the genetic results and the dates ascribe to the fossils be correct? Justify.arrow_forward
