Which dating method relies on the position of rock layers

You argue that there are other differences, such as Your old roommate is in Australia on a one-year study abroad program.

This relative dating technique is based on the principle of: While flipping through the channels, you stop on a television program about primate evolution.The host says that there is a 6-million-year gap in the fossil evidence between the latest Oligocene catarrhines and the earliest Miocene proconsulids, which could mean that primates disappeared from Earth and evolved anew some time later.Your roommate comes running when you start yelling at the television, Your classmate, whose part-time job entails reorganizing the paleoanthropology lab on campus, asks you to take a look at a skeleton that she thinks is from a primate.After noting the absence of a postorbital bar, nails, and an opposable thumb, you tell her that In an argument with your parents, they claim that the only difference between australopithecines and early Homo species is a bigger brain in the latter.When you ask her for more details, she invites you to guess the topic of her project based on this fact alone.You suggest that her project may be about While studying for your physical anthropology midterm, your classmate tells you that the bones of Lucy, a famous australopithecine specimen that dates to about 3.2 million years ago, were dated based on carbon-14 analysis.

You note that this is incorrect because A team of paleoanthropologists has concluded based on skeletal anatomy that the new species they found, Oreopithecus, lived in an arboreal habitat.

This conclusion may have been based largely on the apes’If fossil species A is consistently recovered from geological deposits beneath layers containing fossil species B, then A is considered older than B.

A volcanic eruption on the coast of Japan in 1850 deposits a layer of ash on top of a layer of red clay, and the ash is covered by a layer of silt in a tsunami in 1902.

Archaeologists find a coin between the ash and silt, and they find a small pot between the ash and clay.

Given this sequence of events, which of the following is true?

Your professor is planning to undertake chemical isotope analysis for her latest paleoanthropology project.
