Human Evolution: An Illustrated Introduction
Format: PDF / Kindle (mobi) / ePub
The brief length and focused coverage of Human Evolution: An Illustrated Introduction have made this best-selling textbook the ideal complement to any biology or anthropology course in which human evolution is taught. The text places human evolution in the context of humans as animals, while also showing the physical context of human evolution, including climate change and the impact of extinctions. Chapter introductions, numerous drawings and photographs, and an essential glossary all add to the accessibility of this text.The fifth edition has been thoroughly updated to include coverage of the latest discoveries and perspectives, including:
· New early hominid fossils from Africa and Georgia, and their implications
· New archaeological evidence from Africa on the origin of modern humans
· Updated coverage of prehistoric art, including new sites
· New perspectives on molecular evidence and their implications for human population history.

major milestones for paleoanthropology. Since that time two important advances have taken place with radiopotassium-based dating. The first, developed in the 1960s, allows measurements to be taken in one sample rather than in two separate samples (one to measure potassium, the second to measure argon-40). The rock is initially irradiated with neutrons, which transforms the stable potassium-39 into argon-39; when the rock is then heated, the two argon isotopes, 39 and 40, are released together and
close harmony, with the remarkable design so clearly manifested in creatures great and small being seen as evidence of God’s hand. In addition to design, a second feature of God’s created world was natural hierarchy, from the lowest to the highest, with humans being near the 4 Part One: Human Evolution in Perspective Figure 1.2 The anthropomorpha of Linnaeus: In the mideighteenth century, when Linnaeus compiled his Systema Naturae, Western scientific knowledge about the apes of Asia and Africa
as Lucy (see figure 19.5). Australopithecus afarensis was the oldest known hominin, at 3-plus million years, and was held by many as the stem hominin, ancestral to Homo, perhaps via A. africanus. Again, the evolutionary scenario is rather simple, and the temporal distance between afarensis at a little over 3 million years and the putative origin of the hominin clade at 5 to 7 million years (from molecular data) should 124 Part Four: Hominin Beginnings Recent fossil discoveries Figure 19.4
pattern was apelike; in contrast, it was humanlike in early Homo. He concluded that australopithecines did not move bipedally in the same way as modern humans or even early Homo. An analysis of the trunk of Australopithecus (as seen in Lucy) implies that, however well adapted this species was for bipedal walking, bipedal running was not part of its repertoire.
