How comparisons between the proteins of two species can yield data about their evolutionary relationship?
Take the protein cytochrome C. There is not one amino acid difference in structure between we humans and our close relatives, the chimpanzees. There are 51 differences between humans and single celled yeast in amino acids. We can strongly and simply infer from this data the evolutionary relationship among the three species mentioned here.

What is the significance of identifying ortholog proteins in evolutionary studies?
Identifying ortholog proteins in evolutionary studies is significant because it helps researchers understand the evolutionary relationships between different species. Orthologs are proteins that have a common ancestor and perform similar functions in different species. By studying orthologs, scientists can trace the evolution of these proteins and gain insights into the evolutionary history and relationships between species.
Is water a protein?
what is the relationship between body proteins and water? what is the relationship between body proteins and water?
What is the difference between anatomical embryological and biochemical evidence?
Anatomical embryological evidence refers to similarities in developmental patterns and structures among different organisms, providing insights into their evolutionary relationships. Biochemical evidence involves comparisons of proteins, DNA sequences, and other molecules to understand evolutionary relationships. Both types of evidence can complement each other in confirming evolutionary relationships between organisms.
What does a branch on a phylogenetic tree indicate about the evolutionary relationship between different species?
A branch on a phylogenetic tree indicates the evolutionary relationship between different species. The length of the branch represents the amount of evolutionary change that has occurred between the species, with shorter branches indicating a closer relationship and longer branches indicating a more distant relationship.
What is the relationship between chromosome mRNA and proteins?
The mRNA is transcribed into proteins
What is the most accurate evidence of an evolutionary relationship between two organisms?
The most accurate evidence of an evolutionary relationship between two organisms is the presence of shared genetic similarities, specifically in their DNA sequences. This indicates a common ancestry and evolutionary history between the two organisms.
What is the relationship between body proteins and water?
water degrades proteins
Biochemical analysts use similarities in what as evidence for evolutionary relationships?
Biochemical analysts use similarities in molecules like DNA, proteins, and enzymes as evidence for evolutionary relationships. The more similarities there are between the molecules of different organisms, the closer their evolutionary relationship is believed to be.
What is the relationship between geological and biological evolutionary theories?
They both explain History
What is the relationship between proteins and enzyme?
Enzymes are Proteins that speed up chemical reactions.
What do biologists use to establish whether or not two organisms are of the same species?
Biologists might use a combination of morphological characteristics, genetic analysis, behavior observations, and reproductive compatibility to determine if two organisms are of the same species. These methods help provide a comprehensive understanding of the relationship between different organisms and the boundaries of a species.
What is the relationship between protein and chromosomes?
The mRNA is transcribed into proteins
