Question

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 diversity in space (biogeography)
