Archaeology is the scientific study of past human culture and behavior, from the origins of man to the present. Archeology studies past human behavior by examining the material remains of previous human societies. These remains include fossils of humans, food remains, building ruins, and human artifacts such as tools, pottery, and jewelry. The Origin of Species presents us with a theory of natural selection. This theory is his attempt to explain how the world and its species got to the way we know them now. Through the effects of man and the effects of nature, species have had an ongoing trial and error experiment. It is through this evidence that the natural world has developed beneficial anomalies that sometimes seem too large to be the work of chance. When an animal gains a genetic advantage over its competitors, whether they are of the same species or a completely different genus, the animal has increased its chances of procreation or adaptation. When this animal has this beneficial variant, the advantage becomes theirs, and because of this, the trait is passed on to the animal's offspring. The theory of natural selection is not limited to heritable and beneficial variations in a species. It also depends a lot on population growth and the death of a species. For a species to continue to exist it must ensure certain things. It must first produce more children than survive. If this is not done, the species is obviously destined to become extinct. It is also important that the species propagates at a rate that allows for variance. It can be said that a solid foundation in evolutionary theory is necessary for any attempt to study human evolution. While Feder... in the center of the card... only uses information from the present to interpret the past. Archaeologists also try to experimentally recreate the pattern they find in their research, a technique known as experimental archaeology. Successful reconstructions can become plausible explanations for how the archaeological record was formed. Three important implications for Paleolithic archaeological research on origins and evolution. First, the capacity for behavioral variability that we believe evolved uniquely among recent human populations may be evolutionarily primitive. Second, this capacity for behavioral variability may be shared with now-extinct hominin species. Finally, differences in the capacity for behavioral variability may not explain why these other species went extinct. The case for behavioral variability is strong, but few major problems in evolution boil down to single causes.
