How do scientists use chromosome comparisons to determine the evolutionary relationships among organisms?
Wiki User
∙ 12y ago
Organisms that are closely related usually have very similar chromosomes numbers and a large degree of homology (similarity) beween their chromosomes (but the chromosomes are different enough to maintain genetic isolation).

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 DNA and RNA help scientists determine evolutionary relationships?
Each organism has a specific sequence of DNA, this is what makes up the organism itself appearance and functions. If a sequence in the DNA has changed, so has an aspect of the organism. If there are enough changes over time that a scientist has monitored, then a new or modified species has formed.
Scientists have traditionally drawn evolutionary diagrams in the form of?
a tree
How do scientists determine the evolutionary relationship among species?
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.
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.
Scientists determine evolutionary relationships by looking at breeding behavior geological distribution and structural similarities between organisms true or false?
It is true that scientists determine evolutionary relationships by looking at breeding behavior, geological distribution, and structural similarities between organisms. Scientists can use other criteria to determine evolutionary relationships.
How do scientist infer evolutionary relationships among organisms?
scientists can infer how closely related the organisms are in an evolutionary sense
How do scientists determine the evolutionary relationships among organisms with structural similarties?
study
How do scientists determine the evolutionary relationships among organisms?
Because they love u
Scientists determine evolutionary relationships between animal phyla using evidence from the?
Fossil record
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.
What do scientists use to show evolutionary relationships?
Fish... They open and close there mouth and again, and again etc... Also fish can swim in the sea, there are lots of different types of fish and some can be eaten and yeah laaa !!
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 pieces of evidence that scientists combine to determine evolutionary relationships among species?
Genetic features, morphological features and behavioural features.
Why is it useful for scientists to look at embryonic structures when determining evolutionary relationships?
Sometimes there are similarities in the embryonic stages of organisms that don't exist in the adult stages.
What do modern scientists use in classifying organisms that Linnaeus did not use?
Modern scientists use genetic sequencing, molecular studies, and evolutionary relationships to classify organisms, techniques that Linnaeus did not have access to. These methods provide a more accurate and detailed understanding of the relationships between different species.
What is the evolutionary ancestor ancestor to the fungi?
Scientists have not identified an evolutionary ancestor to fungi.
