Fossils tell us when organisms lived, as well as provide evidence for the progression and evolution of life on earth over millions of years. Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils range in age from 10, to 3.

The major focus of this section is to help learners understand how scientists use deductive reasoning to understand the past. Scientists can never know exactly what happened in the past, but they are able to use various forms of evidence clues to piece together a coherent picture. When evidence from many different areas start to agree with each other it lends more credibility to the theory.
Different forms of evidence, such as that provided by geological records and fossil evidence, will be introduced. Scientists have divided the history of life into different time periods using the geological timescale. In this section we will present the key evidence scientists have used to construct this time scale.
We will discuss the continental drift theory which explains how the continents were formed. We will also briefly touch on the theory of natural selection which explains how one life form can evolve into another over many years by adapting to its changing environment. We will then present the methods by which we are able to determine evolution of life forms over time through examining the fossil record.
The geological timescale is a ‘calendar’ of events in the Earth’s history.

While true, fossils are buried with plenty of clues that allow us to reconstruct their history. In , in Ethiopia’s Afar region, our research team discovered a rare fossil jawbone belonging to our genus, Homo. To solve the mystery of when this human ancestor lived on Earth, we looked to nearby volcanic ash layers for answers. Working in this part of Ethiopia is quite the adventure.

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.

The Fossil Record learning objective — based on NGSS and state standards — delivers improved student engagement and academic performance in your classroom, as demonstrated by research. Over time, layers of igneous and sedimentary rock that pile up on top of each other to form rock strata. The Principle of Superposition tells us the deepest strata are the oldest, and each layer on top of the next gets younger and younger.

Key Terms: paleontology, evolution, fossilization, fossil record, index fossil, taphonomy, cross-cutting relationships, unconformities, fossil succession, rock superposition, original horizontality, geologic time, relative dating, speciation, mass extinction, adaptive radiation. Our Earth has been around for approximately 4. Fossils, or rocks with evidence that life, show that life formed on Earth nearly four billion years ago.
The fossil record helps scientists to understand the history of change over time. We find fossils such as sea shells, imprints of plants and animals, and burrows from worms that crawled through the soil long before man existed. In the high Himalayan peaks we find fossils of life forms that lived in oceans long ago. In many places we see evidence that the Earth’s atmosphere had to evolve before living things could live on land.
In other places, the rock record reveals mass extinctions that occurred when environmental conditions changed so rapidly that organisms could not keep pace with the rate of change. All of these fossils tell us something about the evolution of life on our planet and the evolution of the planet itself. Due to the Earth’s dynamic processes life has adapted to fit available niches.
