Molecular evidence can be used to establish evolutionary relationships by comparing similarities and differences in DNA, RNA, or protein sequences among different species. The more similar the sequences are between two species, the more closely related they are believed to be in terms of their evolutionary history. This helps scientists create phylogenetic trees to show how species are related to each other through common ancestry.

What is molecular evidence?
Molecular evidence refers to the use of genetic material such as DNA or proteins to understand evolutionary relationships between different species. By comparing molecular sequences, scientists can determine how closely related organisms are and study their genetic diversity and evolutionary history. This type of evidence is widely used in the field of molecular biology and genetics to gain insights into the evolutionary processes that have shaped life on Earth.
How does molecular evidence occur?
Take the cytochrome C electron shuttle in the electron transport chain and see how it is highly conserved in form and function among a wide variety of eukaryotes. That is molecular evidence for the relatedness of widely disparate organisms.
What does molecular evidence mean?
Molecular evidence refers to biological data obtained at the molecular level, such as DNA sequences or protein structures. This kind of evidence is used in various scientific disciplines, including genetics, evolutionary biology, and biochemistry, to study relationships among organisms, genetic variation, and other molecular processes.
What is the difference between morphology and molecular evidence?
Morphology refers to the physical characteristics and structures of an organism, while molecular evidence involves studying the genetic material (DNA or proteins) to understand evolutionary relationships. Morphology focuses on external features, such as shape and size, while molecular evidence provides insights into the genetic similarities and differences between species. Both forms of evidence are used in combination to infer evolutionary relationships and taxonomy.
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.

How has molecular evidence affected our understanding of modern evolutionary theory?
It largely supports anatomical evidence and provides more detailed information for specific relationships

Which type of evidence for evolution is most accurate in determining evolutionary relationships-morphology or molecular?
You could never get any type of evidence to prove untrue things...
Which form of evidence is MOST exact in determining the accuracy of a cladogram?
Molecular evidence, particularly DNA and protein sequencing, is the most exact form of evidence for determining the accuracy of a cladogram. This type of data provides detailed insights into the genetic relationships between organisms, allowing for precise comparisons of evolutionary divergences. Additionally, molecular evidence can reveal nuances in evolutionary history that morphological traits may overlook, leading to more accurate phylogenetic trees.
What evidence do biologists use to establish evolutionary traits?
They use the physical changes in physical Form of an Organism, that naturally occur over Time, to do this.
