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"?
During 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?

- 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_forwardWhat observations led Darwin and Wallace to predict the existence of a long-tongued moth in Madagascar?arrow_forwardYou can use plants grown in pots in a growth chamber to investigate many ecological and evolutionary research questions. Identify an interesting ecological or evolutionary research question, then design an experiment to address this question using a plant system. To come up with your research question, think of questions related to topics covered in lecture. The following questions are very general, but might give you some ideas as you develop your own, more specific, question.• Which species in a group of species is the best intraspecific competitor?• Which species in a group of species is the best interspecific competitor? • Is the best intraspecific competitor also the best interspecific competitor?• Does competitive exclusion occur between two species with similar ecological niches?• Does the outcome of interspecific competition change in different environments, or is the best competitor always the best competitor under all environmental conditions?• Similar to the question above –…arrow_forward

Note: On Jun 4th, 1539, Martin Luther discussed with his disciples; a certain new astrologer who wanted to prove that the Earth moves and not the sky, the Sun, and the Moon. Astrologer Nicolaus Copernicus and his heliocentric theory would ultimately displace Earth from the center of the universe. By the late 17th century, among the Western scientific intelligentsia, Earth was no longer the center of the universe.arrow_forward
