What does fossil evidence reveal?

Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. … The resulting fossil record tells the story of the past and shows the evolution of form over millions of years.

How do fossils show evidence of evolution?

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 does the fossil record document?

The collection of fossils and their placement in chronological order is known as the fossil record. It documents the existence, diversity, extinction, and change of many life forms and environmental changes throughout the history of life on Earth.

What does fossil evidence show about Earth’s climate?

Studying fossil pollen and other fossils helps scientists to learn more about climate change. Based on the evidence these fossils provide, we can find out whether or not climate has changed in the past, and how fast and frequently climate changes occurred.

How do fossils provide evidence for behavior?

This behavior is common in some living animals. How can fossils provide evidence for FAMILY BEHAVIOR? Nests of eggs and baby animals show that parents cared for their young. … When a lot of fossils are found together, this gives us evidence that the animals lived together in HERDS.

What are 4 types of evidence that support evolution?

Evidence for evolution: anatomy, molecular biology, biogeography, fossils, & direct observation.

What are the 5 evidence of evolution?

There are five lines of evidence that support evolution: the fossil record, biogeography, comparative anatomy, comparative embryology, and molecular biology.

What are two examples of the fossil record?

Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants. The totality of fossils is known as the fossil record.

What 4 things do Fossil records show?

Fossils are the remains or traces of ancient life that are usually buried in rocks. Examples include bones, teeth, shells, leaf impressions, nests, and footprints. This evidence reveals what our planet was like long ago. Fossils also show how animals changed over time and how they are related to one another.

Why is the fossil record useful?

The fossil record helps paleontologists, archaeologists, and geologists place important events and species in the appropriate geologic era. … Therefore, some discovered fossils are able to be dated according to the strata, a distinct layer of rock, that they are found in.

Why are fossils so hard to find?

Fossils are rare because most remains are consumed or destroyed soon after death. Even if bones are buried, they then must remain buried and be replaced with minerals. If an animal is frozen like the baby mammoth mentioned above, again the animal must remain undisturbed for many years before found.

What can fossils tell us?

By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. Fossils can tell us a lot about the past.

How do we know past climates?

Clues about the past climate are buried in sediments at the bottom of the oceans, locked away in coral reefs, frozen in glaciers and ice caps, and preserved in the rings of trees. Each of these natural recorders provides scientists with information about temperature, precipitation, and more.

What can the fossil record tell us about the behavior of fossil organisms?

The rocks can give clear evidence about ancient climates, and associated fossils indicate possible prey and predator relationships. Trace fossils, such as tracks and burrows, can sometimes be linked with their makers, and then used to look at modes of locomotion and whether animals burrowed or not [4],[5].

How long can it take to prepare a fossil?

However, if you want your remains to become a fossil that lasts for millions of years, then you really want minerals to seep through your bones and replace them with harder substances. This process, known as ‘permineralisation’, is what typically creates a fully-fledged fossil. It can take millions of years.
