Answer: Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
What do they tell us about the process of evolution Class 10?
The preserved remains of animals or plants or other organisms from the distant past are called fossils. These fossils tell us about many extinct animals and also give insights into how the evolution could have taken place.
What are fossils What do they tell?
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.
What examples are there for fossils showing evolution?
For example, dead animals and plants can be preserved in amber , peat bogs, tar pits, or in ice. preserved traces of organisms, such as footprints, burrows and rootlet traces – these become covered by layers of sediment , which eventually become rock.
What are fossils state their importance in the study of evolution with the help of suitable example?
the remains or impression of prehistoric plants or animals embedded in rock and petrified in form. this is called fossils. they are important because they show the types of plants and animals that were on the earth in different times at the past.
What are the basic events in evolution?
Natural selection and Variations are the two basic events in evolution.
What is the importance of fossils in deciding evolutionary relationships?
Fossils provide the knowledge of animals and plants that lived hundreds of years ago which are now extinct. It helps us to compare the organisms that lived in earlier times and their present descendants. They are the connecting link between two groups and help in the study of evolution.
Which is true concerning how fossils are used as evidence?
Which is true concerning how fossils are used as evidence? Fossils cannot be compared to one another but can be compared to living organisms. Fossils can be compared to one another but not to living organisms. … Fossils indicate that the organisms living on these continents today had common ancestors.
Where are most fossils found?
Most fossils are found in sedimentary rock. Sedimentary rock is formed by dirt (sand, silt, or clay) and debris that settles to the bottom of an ocean or lake and compresses for such a long time that it becomes hard as a rock. Limestone and sandstone are types of sedimentary rock that commonly have fossils.
In what era can you possibly find the most recent fossil?
The most recent fossils can be found in Cenozoic era. because they can found in the uppermost layer of the rocks.
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 is the strongest evidence for evolution?
Similar DNA sequences are the strongest evidence for evolution from a common ancestor.
For what purpose is the study of fossils important?
Answer: Studying fossils helps them learn about when and how different species lived millions of years ago. Sometimes, fossils tell scientists how the Earth has changed.
