Concept explainers
Which of the following observations helped Darwin shape hls concept of descent with modification?
(A) Species diversity declines farther from the equator.
(B) Fewer species live on islands than on the nearest continents.
(C) Birds live on islands located farther from the mainland than the birds' maximum nonstop flight distance.
(D) South American temperate plants' are ;,ore similar to the tropical plants of South America than to the temperate plants of Europe.

- What did Darwin see in Galapagos that supported his ideas about the "origin of species"?arrow_forwardWhich of the following statements regarding Darwin and his theory of evolution is false? Darwin noticed that South American species of birds more closely resembled species found in other temperate regions than a European species of birds Darwin was the original and sole developer of the theory of natural selection Darwin proposed that species adapt over time Darwin proposed that natural selection produces changes in species over timearrow_forwardWhich of the following statements regarding Darwin and his theory of evolution is false?arrow_forward
- The origin of species by natural selection given by charles darwin was first published in which year?arrow_forwardDuring Charles Darwin’s voyages, he observed species of plants and animals unique to specific islands, but with similar looking species on nearby islands. How did Darwin explain these similarities and differences?arrow_forwardCharles Darwin proposed that evolution could be explained by the differential reproductive success of organisms that resulted from their naturally occurring variation. Darwin called this process (a) coevolution (b) convergent evolution(c) natural selection (d) artificial selection (e) homoplasyarrow_forward
- In lecture we discussed eight (8) lines of evidence that Darwin used to lay out his argument for the fact of evolution in his book On the Origin of Species (1859). Using your materials from lecture and the last chapter of the "Origin" that we read for section, 1) rank order these lines of evidence based on what you find the most to the least compelling. 2) Be sure to describe each of these lines of evidence and 3) discuss how they are, or not, relevant in the early 21st century. (From old pset1) Evidence Variation in domesticated species and breeding (artificial selection) Hierarchical classification (groups nested within groups) "Unity of type" - modification of the same basic structure (homology) Evident "fit" of organisms to environments (but imperfections) (adaptation) Structures without apparent function (vestigial structures) Similarity of organisms in early phases of development (embryology) Order in diversity through time in the fossil record (paleontology) Order in…arrow_forwardWhich of Charles Darwin’s evolutionary ideas was a speculative hypothesis about the origin of life from non-living matter when he first proposed it, and is still considered a speculative hypothesis today? his populational change hypothesis his gradualism hypothesis his natural selection hypothesis his abiogenesis hypothesis his common descent hypothesisarrow_forwardIn _______________ the selecting agent is the environment, whereas in _______________ the selecting agent is humans. (a) natural selection; convergent evolution (b) mutation; artificial selection (c) homoplasy; homology (d) artificial selection; natural selection (e) natural selection; artificial selectionarrow_forward
- Explain how each of the following contribute(s) to Darwin’s evolutionary theory: fossils; geographic distributions of closely related animals; homology; animal classification.arrow_forwardWhy was Lyell's concept of uniformitarianism, which proposed that the Earth had been going through gradual geological changes over a much longer period of time than previously believed, important for the development of Darwin's ideas about natural selection? Geological catastrophes can reform the landscape and open new niches into which species can adapt and thrive It provided another argument against the Church's explanation for the creation of Earth It explained how vast mountain ranges could form to separate populations It explained the presence of fossils for species that no longer existed An old Earth provides enough time for the gradual process of evolution to take placearrow_forwardHow might an understanding of evolutionary processes help a biologist doing research in (a) the development of a new antibiotic to replace one towhich bacteria have become resistant? (b) conservation of a specific plant in a rain forest?arrow_forward
