Can selection explain the numerous small differences that molecular biologists have found between proteins and other macromolecules?

No. You even see these small differences in the same species. Could be just do to small nucleotide polymorphisms. A neutral change, such as coding for two different proteins made from amino acids doing the same job, such as two hydrophobic amino acids, would not change the function of the protein. This would make the variation invisible to natural selection.

What are the four pieces of evidence that scientists point to as proof of natural selection?
Among myriad others; fossil evidence, artificial selection, biogeographic distribution of organisms and molecular genetics.
What allows natural selection and evolution to occur for a tree?
differences in the characteristics of individual trees
Why are variations in a species needed for natural selection to occur?
What would be selected if organisms did not have differences that lead to better survival and reproduction, or the opposite. That is all natural selection is.
Condition #1 of Darwin's Theory of Natural Selection by Descent with Modification states?
Individuals within a population have differences.
Is artificial selection and natural selection the same at the molecular level?
Technically, yes, but only because they are using virtually the same processes, the only real difference between the two, is like the difference between choosing your own mate and having someone choose your mate for you.
What science was developed later which was found to support Darwin's theory?
Molecular biologists discovered deoxyribonucleic acid (DNA), the molecule that codes for genes. Every organism's genetic makeup is encoded within strands of this molecule, and the science of molecular biology provided an enormous boost for explaining the role of random mutations in evolution. Darwin had done an excellent job in describing the role of natural selection, but the incorporation of the discoveries of molecular biology into evolutionary biology became known as the "modern synthesis."
Who introduce the theory?
Darwin introduced the modern theory of evolution by natural selection, but it was also introduced by Lamark and other earlier biologists but Darwin was first to theorize about natural selection as the mechanism.
Who introduced the evolution theory?
Darwin introduced the modern theory of evolution by natural selection, but it was also introduced by Lamark and other earlier biologists but Darwin was first to theorize about natural selection as the mechanism.
The molecular and structural similarities observed among these organisms is best explained by which of the following?
natural selection
What makes natural selection happen?
Natural selection is driven by differences in reproductive success between variants within the same population.
What are the four pieces of evidence that scientists point to as proof of natural selection?
Among myriad others; fossil evidence, artificial selection, biogeographic distribution of organisms and molecular genetics.
Natural selectionwhat are some of the similarities and differences between artificial and natural selection?
Natural selection is more efficient ad more precise.
What allows natural selection and evolution to occur for a tree?
differences in the characteristics of individual trees

Is the fiollowing sentence true or false Darwin's theory of evolution changed the way biologists thought about classification?
True. With the theory of evolution by natural selection the new science of biology ( at the publication of On The Origin biologists were still naturalists ) could now see that all organisms were related in a nested hierarchy of classification.
