Evaluate the following statements about seeds from two biology textbooks:
I. The seed coat is an adaptation that protects the plant embryo from damage, water loss, and infection.
II. Evolution has come up with a clever solution for protecting plant embryos: seed coats that prevent damage, water loss, and infection.
Do these statements accurately represent the evolution of seeds?
a) Yes, both statements are accurate.
b) No, neither statement is accurate.
c) Only the first statement is accurate.
The Swedish botanist Carolus Linnaeus was the first taxonomist to argue that, contrary to Aristotle:
humans and horses should be classified in the same kingdom (Animalia)
humans and apes should be classified in the same order (order Anthropomorpha, or Primates)
humans and goats should be classified in the same kingdom (Animalia)
humans and cats should be classified in the same order (order Anthropomorpha, or Primates)
humans and dogs should be classified in the same kingdom (Animalia)
What did Darwin see in Galapagos that supported his ideas about the "origin of species"?

- You have access to the sequence genomes for moss and the lycophyte Selaginella. Your goal in analyzing the data is to write a ground-breaking paper that answers an important question about the evolution of plants. What questions would you try?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_forwardWhat were some of Darwin's discoveries on Galapagos?arrow_forward
- Which of the following observations helped Darwin shape hisconcept of descent with modification?(A) Species diversity declines farther from the equator.(B) Fewer species live on islands than on the nearestcontinents.(C) Birds live on islands located farther from the mainlandthan the birds’ maximum nonstop flight distance.(D) South American temperate plants are more similar to thetropical plants of South America than to the temperateplants of Europe.arrow_forwardIn your own words, what did Darwin mean by an "abominable mystery" as it related to angiosperm evolution.arrow_forwardHow did darwin disproved lamarck?

- How does artificial selection differ from natural selection? Do you think the ancestors of lettuce had such soft, nonbitter leaves? Could today’s lettuce plants survive in natural conditions?arrow_forwardIn 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_forwardWhat observations led Darwin and Wallace to predict the existence of a long-tongued moth in Madagascar?arrow_forward
