Taxonomy uses the Linnean system: > Each species has a two-part name (aka binomial) > Species are organized in broader and broader groups of organisms. Question: Can you identify the proper way(s) to write a species name? a. Homo sapiens b. Homo sapiens c. homo sapiens d. Homo sapiens e. HOMO sapiens f. Homo sapiens g. homo sapiens h. homo Sapiens i. Homo Sapiens Sorting Homology from Analogy A potential problem in constructing a phylogeny Is mistaking similarity due to convergent evolution, (an analogy), for a homology. Convergent evolution when different species living in different, but similar environments develop similar (analogous) adaptations in response to a common problem Remember . homology is due to common or shared ancestry. A phylogeny is determined by a variety of evidence including - fossils, - molecular data, - anatomy, - and other features. A phylogenetic diagram or cladogram is construc ...

Homo Sapiens Essay
University of Iowa, PREHISTORY 101
Excerpt: ... Kyle Goro October 25, 2006 The Origins of Homo Sapiens Sapiens "Understanding the transition from archaic populations of Homo sapiens to the anatomically modern form, H. s. sapiens, is arguably the highest priority on anthropological research on the later Pleistocene (Stiner 1993:55)." This is cause for considerable debate over the origin of our species, Homo sapiens sapiens. The origin of modern Homo sapiens is not yet resolved. Two major scenarios have been proposed. The difference between the two is basic, but very influential on the meanings behind prehistory studies. The question at hand is weather all modern humans evolved in parallel from earlier populations in Africa, Europe and Asia, or an isolated population of early humans evolved into modern Homo sapiens , and this population succeeded in spreading across Africa, Europe and Asia. Putting this question to rest will bring us one step closer to achieving the ultimate goal of anthropology, According to Harris (1989:2), to "adopt a broad view of the tot ...

Other than that, its seems to have a Sagital Crest and based on the picture a rough side for muscles to attach to. 7. Observe the Steinheim skull or any other non-Neanderthal specimen of archaic H. sapiens. Make a list of those characters that seem erectus-like and another list of those characters that seem sapiens-like. The cranial capacity of this specimen is about 1000 cc. Erectus -brow ridge -large eye sockets Sapien -smaller brow ridge - no pertusion of the mandible 8. Compare Neanderthal crania (Figures 11.33 and 11.34) with the crania of modern homo sapiens (figures 11.35 and 11.36). Make a list of differences you observe. Some major differences between the Neanderthal crania and modern homo sapiens are the skull texture. The skull of the Neanderthal is much rougher and has many little crevices compared to the s ...

Excerpt: ... jor environmental changes Hominids as fossils Why so rare? Environment - grassland - not conducive for fossilization Need bogs or lakes - very rare then When hominids died, bones rapidly scavenged Makes hominids among rarest of fossils Early Modern Homo sapiens Anatomically modern humans are classified as Homo sapiens sapiens. Every human today belongs to this variety of Homo sapiens . They first began to appear 120,000-100,000 years ago in association with technologies not unlike those of the early Neanderthals. It is now clear that they did not come after the Neanderthals but were their contemporaries. Compared to the Neanderthals and other late archaic Homo sapiens , modern humans generally have more delicate skeletons. Their skulls are more rounded and their brow ridges protrude less. They also have relatively high foreheads and pointed chins. Climate Change Killed Neandertals, Study Says What are the alternatives: 1. Homo sapiens killed them 2. Loss of food through extinctio ...

HOWEVER, 99% of our DNA and Chimp DNA are identical! Two modern chimps, we are the third one. HOW DOES THIS EVOLUTIONARY MIRACLE HAPPEN WITH THE SAME DNA? -Has little to do with new genes. -Most of the key mutations control rates and patterns of development -increasing brain size. What it takes is let the developmental sequences run longer. However, there are limits. New things become possible. -bigger proportions of our body. As adults we have the features of juvenile apes.
