A fossil is the preserved remains of a dead organism from millions of years ago. Fossils are found in rocks and can be formed from:. Fossil remains have been found in rocks of all ages. Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms in the newest rocks. This supports Darwin’s theory of evolution , which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils.

By studying fossils, scientists can learn how much or how little organisms have changed as life developed on Earth. There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. What traces there were may have been destroyed by geological activity. This is why scientists cannot be certain about how life began.

Fossils provide a snap shot of the past and allow us to study how much or how little organisms have changed as life developed on Earth. Evolutionary trees are used to represent the relationships between organisms. Branches show places where speciation has occurred, and a new species has evolved. In this evolutionary tree, species A and B share a recent common ancestor.

Fossils. Fossils are the preserved remains or traces of living things. Fossils provide clues as to how life has changed over time.

However, “relative” dating or time can be an easy concept for students to learn. Once they are able to manipulate the cards into the correct sequence, they are asked to key a similar sequencing activity using fossil pictures printed on “rock layer” cards. Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata. Once students begin to grasp “relative” dating, they sir extend their knowledge of geologic time by exploring radiometric dating and developing a timeline of Earth’s history.

Idea major concepts are part of the Denver Earth Science Project’s “Paleontology and Dinosaurs” module written for students in grades. Extinction of species is common; most of the species that have lived on the earth sir longer exist. The complete “Paleontology and Dinosaurs” module takes approximately four weeks to teach. The “Who’s On First?

Scientific measurements such as radiometric dating use the natural radioactivity of certain elements answer in rocks to help determine their age. Scientists also use direct evidence from observations key the rock layers themselves to help determine the relative age of rock layers. Specific rock formations are indicative of a particular type of environment existing when the rock was being formed.

The fossil record is one of the most obvious pieces of evidence for evolution. Fossils have been known since human history began, and Aristotle first noted the similarity between fossils and living animals, leading him to conclude that fossils represented deceased creatures, a view supported by Leonardo da Vinci. By the 19 th century, people were increasingly beginning to appreciate that some fossils represented extinct animals, and that their positioning in the rocks appeared to represent that passage of time.

Now there is also ample evidence from molecular genetics and radiometric dating that the fossil record does represent the evolutionary history of life on Earth. Despite this, creationists still continue to argue otherwise. Some have suggested that the fossil record represents animals killed during one or more biblical floods, however this is incongruent with the evidence available. Fossils usually only preserve certain parts such as bones, seeds, teeth and shells; parts that were mineralised prior to death.

Trace fossils, by contrast, are fossilised marks that were created while the animal or plant was alive, such as a footprint.
