A fossil is defined as any trace of a past life form.Thus, although wood, bones, and shells are the most common fossils, under certain conditions soft tissues, tracks and trails, and even coprolites (fossil feces) may be preserved as fossils. This is an informational tour in which students gain a basic understanding of geologic time, the evidence for events in Earth’s history, relative and absolute dating techniques, and the significance of the Geologic Time Scale.The science that studies human cultures is called anthropology.In trying to learn about racial differences, human origins, and evolution, the physical anthropologist studies fossil remains and observes the behavior of other primates.Primates are an order of mammals that includes human beings as well as apes and monkeys.Human kinship relations through marriage are commonly called "affinity" in contrast to the relationships that arise in one's group of origin, which may be called one's descent group.
Paleontologists study fossils and attempt to use them to reconstruct the history of the Earth and the life on it.
Another difference between the two traditions is the Christian belief in the centrality of the crucifixion of Jesus as a single event that some believe acts as the atonement of sins, and its direct contrast to Buddhist teachings.
Though some early Christians were aware of Buddhism, which was practiced in both the Greek and Roman Empires in the pre-Christian period, the majority of modern Christian scholarship has roundly rejected any historical basis for the travels of Jesus to India or Tibet or direct influences between the teachings of Christianity in the West and Buddhism, and has seen the attempts at parallel symbolism as cases of parallelomania which exaggerate resemblances.
By the early second century, post-apostolic Christian theology had taken shape, in the works of authors such as Irenaeus, although Christianity is seen as the fulfillment of Jewish prophecy regarding the "Messiah" which dates back much further.
Starting in the 1930s, authors such as Will Durant suggested that Greco-Buddhist representatives of Emperor Ashoka who traveled to Syria, Egypt and Greece may have helped prepare the ground for Christian teaching.
