Tool use by our early ancestors is one such adaptation.At the onset of the 20th century, most scientists had accepted the great antiquity of the earth, the theory of evolution and that humanity had evolved from an ape ancestor, but by 1908 the fossil evidence of early man was scarce.Biologists included principles from genetics in evolutionary theory during the 1920s and 1930s.Scientists now have accurate methods (see below ) for dating fossils.methods rely on characteristic faunal and geological patterns to bracket the period when the fossil existed.
