How do scientists determine the evolutionary relationship among species?
Wiki User
∙ 7y ago
They use a taxonomic map to help classify organisms. The placement of organisms on this was originally based on similarities between species. Today we are able to look at their actual genes, which has resulted in a better understanding of evolutionary relationships - or the lack of them- and has resulted in some re-classification.

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 can help to determine evolutionary relationships between species?
When two species evolve together, having some relationship while evolving, they both leave traces of what the relationship was in their genetics. For instance, if you see one species with huge teeth, and another with thick skin, one might draw the conclusion that the relationship encompassed one species trying to eat the other.
Current details about the evolutionary process?
Scientists currently think that the evolutionary process is ongoing. Species that cannot adapt do not survive; those that can change and evolve are more successful.
Why would you infer that two species that look similar share a common evolutionary history?
scientist compare body structures development before birth and DNA sequences to determine the evolutionary relationship among organisims
What organelles are used in investigating evolutionary relationships?
Mitochondria and ribosomes are the organelles useful in investigating potential evolutionary relationships. For example, mitochondria can be used to determine relatedness between individuals and species.
Is a type of evidence used by scientists to determine evolutionary relationships?
The evidence do scientist use to determine evolutionary relationships by scientist have combined the evidence from DNA, protein structure, fossils, early development, and body structure to determine the evolutionary relationship amoung species.
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 3 ways to determine the phylogenetic relationship among species?
DNA analysis is commonly used to determine the similarity between two species. From this, we can infer the evolutionary relationship of those species.
What are 3 pieces of evidence that scientists combine to determine evolutionary relationships among species?
Genetic features, morphological features and behavioural features.
Which type of fossil evidence helps determine the evolutionary relationship between two hominid species?
Teeth and Skull Size
The number and structure of what can help to determine evolutionary relationships between species?
The number and structure of chromosomes help determine evolutionary relationships between species. Chromosome comparison helps to provide evidence of the relationships in a species.
How do scientists get information on the evolutionary history of a species?
they are classified more closely together
What evidence do scientists use to learn about the evolutionary history of a species?
I dunnooo :S
How do you determine the evolutionary relationships among species?
examining the fossil records.
What evidence do scientists use to make phylogenetic trees?
Phylogenetic trees represent hypotheses about the evolutionary relationships among a group of organisms. A phylogenetic tree may be built using morphological (body shape), biochemical, behavioral, or molecular features of species or other groups.
The number and structure of can help to determine evolutionary relationships between species?
chromosommes
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.
