What is DNA DNA hybridition?
DNA hybridisation is where DNA is compared from different species to determine how closely species are related
Why do scientists combine evidence from fossil fuels body structures and early development and DNA and protein?
Scientists want to determine the evolutionary relationships among different species.
What are some clues scientists use as evidencece for evolution?
DNA can be used to match two species and determine if they are related or share a common ancestor. In addition, the existence of DNA itself is proof for evolution on a large scale - virtually all organisms share the same nucleic acid as the genetic code, leading scientists to the conclusion that all species shared a common ancestor at one time.
How do scientists determine the living relatives of a fossil?
They look for patterns in the morphology of the organisms. This science of pattern recognition between species is called phylogeny.
Why is DNA analysis suck a good tool for classifying organisms?
The knowledge of DNA makes for more accurate classification of organisms because the scientists can examine certain species of organisms and see if there are related or closely related to determine weather or not they can be classified in the same group or not.
A term that describes the number and variety of species that live in an area?
some factors that determine the number of species in an area. some factors that determine the number of species in an area.
When scientist try to do determine how closely related species are what evidence do they examine?
Scientists examine the bones of the species or the species body parts or the entire body. p.s good luck with the question if this didn't help ....... lol good luck duck
What tool can help scientists to determine ancient species became extinct?
fossil record
What 2 factors determine the evolution of a species?
Natural selection and traits
What factors determine whether a species can be presented in a place?
The weather,food supply
What is DNA DNA hybridition?
DNA hybridisation is where DNA is compared from different species to determine how closely species are related
What type of diagram do scientists use to show how species are related?
Wherever they're found, all living things are related because they all share a common ancestor. To show how species are related, scientists create diagrams called cladograms. Like a family tree, a cladogram shows close and distant relatives. Scientists call the family tree for all species on Earth the "Tree of Life."
Why do scientists combine evidence from fossil fuels body structures and early development and DNA and protein?
Scientists want to determine the evolutionary relationships among different species.
How do you determine if species are related?
These days, with DNA testing. Earlier, by looking for detailed similarities.
What is an method of comparing traits in related species to determine ancestor-descendant relationships?
cladistics
How does analysis of DNA help scientists establish an evolutionary classification scheme?
Analysis of DNA helps scientists establish an evolutionary classification scheme by comparing the genetic sequences of different organisms. The more similar the DNA sequences are between two species, the more closely related they are believed to be. By studying the similarities and differences in DNA, scientists can determine how different species are related to one another and create a classification scheme based on their evolutionary relationships.
