When scientists try to determine how closely related a species are, what evidence do they examine? The type of evidence to be used would be:protein structure, fossils, early development and body structure. You would used combine evidence of the species and draw a Branching tree.

What provides evidence for closely related species?
Molecular biology.
DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.
How do scientist determine how closely related organisms are?
Generally, the longer ago the last common ancestor lived, the less the organisms have in common. ... Scientists can compare the DNA of two organisms; the more similar the DNA, the more closely related the organisms.
How do scientists use comparative anatomy as evidence for evolution?
Scientists compare the anatomy, embryos, and DNA of living things to understand how they evolved. Evidence for evolution is provided by homologous structures. These are structures shared by related organisms that were inherited from a common ancestor. Other evidence for evolution is provided by analogous structures.
What are closely related species?
In biology, a species complex is a group of closely related organisms that are so similar in appearance that the boundaries between them are often unclear. ... As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use.
What is the best way to determine how closely organisms are closely related group of answer choices?
2. What is the best way to determine if two species are closely related? The best way is to compare the DNA of the two species. The more nitrogenous bases and amino acids two species have in common, the more closely related they are.
How do scientists determine that they are more closely related to each other than they are to the other organisms here?
Two species are more related if they have a more recent common ancestor, and less related if they have a less recent common ancestor.
What do scientists predict when they compare the biochemistry of closely related organisms?
2 Answers. The similarities among biochemicalls tell about the theory of evolution.
Why would you expect organisms with similar anatomy to be more closely related?
Organisms with similar anatomical features are assumed to be relatively closely related evolutionarily, and they are assumed to share a common ancestor. ... Since these structures are so similar, they indicate an evolutionary relationship and a common ancestor of the species that possess them.
How does comparative embryology show evidence of evolution?
The field of comparative embryology aims to understand how embryos develop, and to research the inter-relatedness of animals. It has bolstered evolutionary theory by demonstrating that all vertebrates develop similarly and have a putative common ancestor.
What evidence have you discovered that explains how comparative anatomy helps with understanding the evolutionary history of bats and birds?
The wings of bats and birds are both derived from the forelimb of a common, probably wingless, ancestor. Both have wings with bone structures similar to the forelimbs of ancestral and current tetrapod, or four-legged, animals.
Which of the following is the most appropriate way to determine how closely related two groups?
Which of the following is the most appropriate way to determine how closely related two groups are using evolutionary tree? Counting the number of nodes between the groups of interest.
What is it called when two species are closely related?
Symbiosis is a term describing any relationship or interaction between two dissimilar organisms. The specific kind of symbiosis depends on whether either or both organisms benefit from the relationship.
How are species related?
Overwhelming evidence shows us that all species are related--that is, that they are all descended from a common ancestor. ... Today, we realize that most such resemblances--in both physical structure and embryonic development--are expressions of shared DNA, the direct outcome of a common ancestry.
Which information would best help scientists verify the relationships among the organisms shown above?
Q. Which information would best help scientists verify the relationships among the organisms shown above? The organisms' DNA.
What types of information provide the clues that scientists use in investigating evolutionary relationships?
What types of information provide the clues that scientists use in investigating evolutionary relationships? Fossils, biogeographical studies, comparative anatomy, and molecular techniques such as sequencing of proteins and DNA provide the evidence that scientists use in investigating evolutionary relationships.
How are the similarities in DNA sequences between organisms used to determine how closely different species are related?
Molecular clocks are used to determine how closely two species are related by calculating the number of differences between the species' DNA sequences or amino acid sequences. ... On the other hand, animals may look similar but can have very different DNA sequences and evolutionary ancestry.
