Fossils show that there have been many?
Fossils show that there have been many different species of organisms that have lived on Earth throughout its history. These fossils provide important clues about the evolution and biodiversity of life on our planet.
How do you know anything at all about the early episodes of life on earth?
Scientists study fossils, geological records, and genetic data to understand early life on Earth. Fossils provide evidence of ancient organisms, while geological records show changes in environments over time. Genetic data helps trace the evolution of species and how they are related to each other.
What can rock fossils and original remains show about earths past?
it can show the futur
How does the position of fossils in layers show evolutionary changes?
Assuming the layers aren't deformed, the lowest deposition layers are the earliest. Later deposition layers accumulate on top of the earlier layers. Thus, the lowest layers have the earliest fossils, and the highest layers have newer fossils. By comparing the features of early and late fossils of a species, you can determine some of its evolutionary changes. Of course, not all features survive in a fossil - soft tissues, for example.
How does the field of genetics contribute to the study of evolution today?
Genetics is a very important part of biological evolution because it allowed us to study the genetics of various organisms and see how related to other species and to us they were. From this, we could work out how long it has been since two species diverged from a common ancestor based on how genetically different or similar the two species were.
How are fossils an example of evolution?
Fossils show certain species underwent small changes over a period of years the rock in which the fossil is encased dates the fossil and so they can put them in order to show the progression of the physical changes
How are fossils used to show changes in Antarctica?
plant fossils (glossopteris) were found there.
Fossils show that there have been many?
Fossils show that there have been many different species of organisms that have lived on Earth throughout its history. These fossils provide important clues about the evolution and biodiversity of life on our planet.
How do fossils give proof of evolution?
Fossils show clear evidence that the earliest human species had many apelike features & have evolved over the years.
Closely related species show more in nucleotide sequences than distantly related species?
similarity

What do evolutionists believe fossils prove?
Fossils show that the organisms that were around a long time ago were not the same ones that are around now, indicate that life changes over time.
What are used as evidence for evolution?
Fossils. These show the incredible amount of time required to turn early life forms into stone. Studying the fossils, one can see the similarities and evolution of species over time. UNREST.

What type of evidence sHow is that evolution has occurred?
Evidence for evolution includes the fossil record showing transitional forms, comparative anatomy showing similarities in structures among different species, genetic similarities among different species, and observed instances of natural selection leading to changes in populations over time.
What is descent with modification. and how do fossils help show it?
Descent with modification is a principal that is closely linked to natural selection. It means that the descendants of a parent species will have been slightly modified, and their descendants will be slightly modified, and so on. Natural selection is the engine that drives this modification- and ensures that this change is in a direction that better suits the species to its environment. In this way, species are constantly changing, though extremely slowly. The geological record can show how a certain species has slowly changed over time. As we follow a species through hundreds of thousands of years, parts of its organization become modified as the species becomes better suited to its environment, or to other environments that allow it to extend its range. These changes in physical aspects can be seen in fossils and show, for example, how a fin for swimming evolved into a leg for walking.
