What are the structurall and biochemical similarities of animalsand all living organisms?

The structural and biochemical similarities among living organisms are best explained by Darwin's conclusion: Living organisms evolved through a gradual modification of earlier forms --- descent from a common ancestor.

On what basis are organisms generally classified?
The underlying basis of taxonomic groupings of organisms is the similarities of their anatomical, behavioral, cellular, and biochemical characteristics. Ideally, taxonomic groupings reflect shared ancestry.
What is biochemical processes?
Chemical processes occurring in living organisms.
Why the homologous structures are evidence of evolutionary relationship?
They show similarities between organisms structure. if the similarities are large then it shows that those organisms share a common ancestor.
What do all organisms have that is invisible because it involves small differences in biochemical processes?
Genetic Variation
What do you know about organisms that share many anatomical similarities?
Anatomical similarity refers to members of the same class of animals tend to have similar structures and organs.Anatomical similarities between organisms are limited to physical similarities that serve similar functions.
What similarities and differences could you look at when you classify organisms?
Organisms are classified by their: * physical structure (how they look) * evolutionary relationships * embryonic similarities (embryos) * genetic similarities (DNA) * biochemical similarities
What are domains based on?
This system is based on biochemical analysis and comparison of the RNA of organisms and attempts to group them according to those similarities.
What is the definition of biochemical similarities?
A generalization of the concept of molecular evolution is the observation that the basic biochemical processes of all organisms are very similar, despite the apparently arbitrary nature of many of these processes

An example of Biochemical similarity between two different organisms?

Is classification the arrangement of organisms into orderly groups based on their similarities?
Organisms are classified based on their various similarities, and also based upon their relationship to other organisms.
Do micro organisms have a chemical reaction?
Biochemical reactions are also involved in microorganisms.
Why is biochemical evidence of evolution considered to be indirect?
I do not know. I can look at shared biochemical pathways and see direct evidence of common ancestry with other organisms.
What is a bioseparation?
A bioseparation is a separation of the products of a biochemical reaction without damaging the organisms concerned.
How do scientists use scientists use structural similarities to determine the evolutionary relationship?
They see similarities with structures between modern day organisms and older organisms.
Why the homologous structures are evidence of evolutionary relationship?
They show similarities between organisms structure. if the similarities are large then it shows that those organisms share a common ancestor.
