5.1 - Evidence for Evolution Exam Questions With Verified Answers. Biological evolution? - answerA change in the allele frequency of a population's gene pool over successive generations how are heritable characteristics stored and transfered? - answerGenes, alleles Fossils as evidence for evolution> - answerA fossil is the preserved remains or traces of any organism from the remote past Preserved remains (body fossils) provide direct evidence of ancestral forms and include bones, tee...

Sections 2.1 - 2.5 summarize evidence for Evolution. Some evidence had been available to Darwin and his contemporaries, but the majority of the evidence came later, in the 20th century. For example, Darwin was aware of the following: Answer Vestigial structures Geological evidence for mass extinctions Succession in the fossil record Structural and developmental homologies The evidence from biogeography, based on occurrence of closely related species in groups of islands (such as the Galapago...

According to one article we read early in this class what new name has been proposed to describe the geological time period we are now in? a. Infozoic b. Computational Age c. Degradozoic d. Anthropocene correct answer: d. Anthropocene If humans are causing enough change to merit the designation of a new epoch according to the authors of the paper we read and your ideas in class which one of the following may NOT be one of the things that future geologists will see in the rock record from...

Geologic Time Scale correct answersthe "calendar" for events in Earth history. It subdivides all time into named units of abstract time called—in descending order of duration— eons, eras, periods, epochs, and ages. ● Thanks to the work of early geologists like Steno, Arduino, and Smith, modern scientists have used these and other clues to create what we now call the Geologic Time Scale,or GTS. ● The GTS has been reworked many times to reflect the latest knowledge of Earth's histo...

Which of the following is an exogenic process? Volcanism Weathering Earthquakes Flows of heat and materials in the mantle - Weathering Which of the following is an endogenic process? Weathering Glacial erosion Volcanism Stream deposition - Volcanism Uniformitarianism assumes that mountains, plains, and canyons formed by catastrophic events. catastrophic episodes have regularly occurred. Earth is quite young and is shaped by dramatic events. the same physical processes we see today ...
