New discoveries have filled in the gaps, and shown us in unimaginable detail the shape of the great ‘tree of life’.Darwin and his contemporaries could never have imagined the improvements in resolution of stratigraphy that have come since 1859, nor guessed what fossils were to be found in the southern continents, nor predicted the huge increase in the number of amateur and professional paleontologists worldwide.Early geologists, in the 1700s and 1800s, noticed how fossils seemed to occur in sequences: certain assemblages of fossils were always found below other assemblages. Since 1859, paleontologists, or fossil experts, have searched the world for fossils.In the past 150 years they have not found any fossils that Darwin would not have expected.Similarly, materials of human origin are also deposited onto the earth’s surface.In archaeological sites, natural and human-generated materials occur together in layers.Thus creationists and others who invoke perceived weaknesses in radiocarbon dating as justification to cast doubt on the great age of the earth are either uniformed on very basic scientific facts, or else are highly being disingenuous to their audience.

These skeptics do not provide scientific evidence for their views.We have a limited supply of the out-of-print books titled "Selected Preforms, Points and Knives of the North American Indians" written by Greg Perino, who was considered by many to be "The Master" in the artifact authenticating world.These can be ordered by simply clicking on the email link below, and by sending the email.some of these are Andice, backed knives, Dawson, First view, Goshen, Howard county, Massard, Nebo hill, Paisano, Raccoon, Stockton, Turin, Ulu, and Washita northern variety.Volume 3 starts with the Acatta arrowhead type and ends with the Zora type, with a total of 256 point types covered.Because of this relatively short half-life, radiocarbon is useful for dating items of a relatively recent vintage, as far back as roughly 50,000 years before the present epoch.
