How do scientists use similarities in early development as evidence for evolution?
By examining fossils and by determining their relative and absolute ages, scientists have collected evidence that supports the theory that species changed over time.
What evidence do scientists use to create branching tree diagrams?
the use DNA evidence. So they check the dna's of organisms and compare them to others and see whos closely related to who..
What types of evidence do scientists use to support evolution?
Fossils, D.N.A., vestigial organs or structure, same structure diffrent function.
What evidence do scientists use to prove that evolution has occurred?
Simple example. You know hair color is under genetic control. Two types, blond ( which is recessive ) and brown ( which is dominant ) exist in our population. These two alleles are in a 75% to a 25% frequency. ( dominant to recessive ) if that frequency changed to 60% to 40% you could say that evolution had taken place. Evolution is the change in allele frequency in a population of organisms over time. ( example very simplified ) PS Scientist do not prove things. They support their work with the evidence.
What three examples do scientists use to prove evolution?
The divergence among the same types of animals, like pigeons and penguins are both types of birds... The fossil record showing the transition between animals... The fact that fossils are found in order, mammals only above birds, birds above reptiles, reptiles above fish, never a rabbit under a dinosaur
How are fossils used to helps understand the history of earth?
Scientists can use fossils to learn about what happened about what Earth was like in the past. A fossil is any evidence A fossil is any evidence that life once existed in a place.
How scientists estimate the age in years of a fossil?
Scientists can use carbon dating to determine the age of a fossil.
What evidence would a scientists use to determine the absolute age of a fossil found in sedimentary rock?
The Igneous intrusions and extrusions near sedimentary layers.
What are the differences between the fact and evidence?
A fact is an objective truth or reality that can be proven or verified. Evidence, on the other hand, is information or data that supports a claim or proposition. Facts are concrete and incontrovertible, while evidence is used to establish the truth of a statement or argument.
What do scientists use the fossil record for?
Recording fossils No.
What evidence do scientists use to study the ancient dinosaur?
Scientists use mainly fossils.
Scientists use tools to?
...prove hypotheses, for one.
What do scientists use to study macro evolution?
The fossil record
What do scientists often use to study macroevolution?
The fossil record
How do you use empirical evidence in a sentence?
the scientists had empirical evidence waiting to be answered
Why do scientists use fossil fuels?
dont really know xx ;)
How long will fossil fuels be available for your use?
scientists show that fossil fuels will be nowhere to be found in the next 20 to 30 years
