A Relative Dating Activity is a hands on exercise which introduces students to the concepts of sequencing and using fossils to establish relative dates for rock strata. In the first part of the activity, students are asked to sequence cards by identifying and ordering overlapping letters found on the cards. In the second part of the activity, students progress to dating rock layers by sequencing fossils found in the different strata.
However, these methods require ancient remains to have certain elements Moreover, relevant fossils or artifacts have not been discovered for all geneticists are helping to build a more refined timeline of human evolution.
Fossils are physical evidence of preexisting organisms, either plant or animal. The most common and obvious fossils are the preserved skeletal remains of animals. Other fossils, which are also evidence of past organisms, include leaf impressions, tracks and trails, burrows, droppings, and root casts. Microfossils are the microscopic skeletons of previously existing plants or animals, and their examination requires an optical or an electron microscope for close study.
A very small fraction of the organisms that have lived on the Earth is found in the fossil record: Many did not possess skeletons or other hard parts that could be preserved; many did not survive the process of fossilization, wherein skeletons and tissues are replaced by minerals; and many were subsequently destroyed either by chemical or physical processes such as recrystallization, metamorphism, or erosion.
Fossils of any kind are useful in “reading the rock record,” meaning they help us decipher the history of the earth. They can help us determine the geologic age and environment the paleoenvironment in which they were deposited. Finally, and if the fossil record is complete enough, their study can help us better understand the evolution or progression of life through geologic time.
Our understanding of the meaning of fossils is based on the accumulated knowledge from previous generations of investigators who carefully recorded the identity and distribution of fossils from numerous geologic exposures or samples from wells and recorded their findings in the scientific literature. When the regional or global distribution of fossils through geologic time is taken into consideration, we can gain important insights into such phenomena as continental drift, community migration, and climatic paleoclimatic reconstruction.

Scientists have discovered a wealth of evidence concerning human evolution , and this evidence comes in many forms. Thousands of human fossils enable researchers and students to study the changes that occurred in brain and body size, locomotion, diet, and other aspects regarding the way of life of early human species over the past 6 million years. Millions of stone tools, figurines and paintings, footprints, and other traces of human behavior in the prehistoric record tell about where and how early humans lived and when certain technological innovations were invented.
Study of human genetics show how closely related we are to other primates — in fact, how connected we are with all other organisms — and can indicate the prehistoric migrations of our species, Homo sapiens , all over the world. Advances in the dating of fossils and artifacts help determine the age of those remains, which contributes to the big picture of when different milestones in becoming human evolved.
Exciting scientific discoveries continually add to the broader and deeper public knowledge of human evolution.

With your partner, arrange the fossil cards from oldest to youngest. Hint: Start with fossil card 2; you know this fossil is the oldest fossil record because it is the only fossil with a single type of organism.
After an organism becomes extinct, it will no longer appear in the later younger fossil samples. In the table below, record your samples in order from oldest to youngest starting with fossil 2 on the bottom and work up the table. Write the fossil names in order by age from left oldest to right youngest across the top row of the table. Drawing a representation of the fossil organism along with the name helps.
Hint: Examine the fossil cards carefully to determine where each organism appears in the fossil record.
