Studies using radiometric dating Sex gerl
They were made by all previous members of the genus, starting with relatively crude tools made by Homo habilis and Homo erectus.
In Europe, the large-brained Neanderthal Man (Homo neanderthalensis) made tools of high quality, and was in turn outshone by the many tools made by our own species.
The age ended when humans began to make small, fine tools (Mesolithic) and finally when plant crops and have other types of agriculture (Neolithic).
Ninety-five percent of the activity of Oxalic Acid from the year 1950 is equal to the measured activity of the absolute radiocarbon standard which is 1890 wood.
adaptation: Any heritable characteristic of an organism that improves its ability to survive and reproduce in its environment.
Also used to describe the process of genetic change within a population, as influenced by natural selection.
adaptive landscape: A graph of the average fitness of a population in relation to the frequencies of genotypes in it.
Peaks on the landscape correspond to genotypic frequencies at which the average fitness is high, valleys to genotypic frequencies at which the average fitness is low. adaptive logic: A behavior has adaptive logic if it tends to increase the number of offspring that an individual contributes to the next and following generations.
If such a behavior is even partly genetically determined, it will tend to become widespread in the population.
