As This Chapter Makes Clear, There Are Many Issues Within

question 58

Multiple Choice

As this chapter makes clear, there are many issues within hominin evolution that remain open to debate. One of them regards the Kenyanthropus fossil found by Maeve Leakey, who argues that at least two hominin lineages existed as far back as 3.5 million years (the other being A.afarensis) . Taxonomic "splitters" tend to agree with her interpretation, while taxonomic "lumpers" disagree. These two interpretations highlight

• A) the distinction between those who stress diversity and divergence, and those who focus on similarities across fossil finds.
• B) that more fossil evidence isn't necessarily better, because it only leads to more misinterpretation.
• C) the distinction between creationists and evolutionists.
• D) the difference between those who consider bipedalism as the key hominin feature, and those that consider large brain size the key feature.
• E) that not all paleoanthropologists value human diversity.
