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 else can I help you with?
Scientists who study evolution at or below the species level are most likely?
evolutionary biologists or population geneticists. They typically focus on understanding how genetic variation within and between populations drives the evolutionary changes that lead to speciation and adaptation. This involves studying processes such as natural selection, genetic drift, gene flow, and mutation at the level of individual organisms and populations.
What are the scientists who study evolution called?
Scientists who study evolution are called evolutionary biologists. They research the processes of genetic change and natural selection that drive the diversity of life on Earth.
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.
How does molecular biology provide evidence for evolution?
Molecular biology provides evidence for evolution through the study of genetic sequences, comparing similarities and differences between organisms at the molecular level. By analyzing these sequences, scientists can trace evolutionary relationships, determine common ancestry, and understand how species have evolved over time through genetic mutations and natural selection. This molecular evidence supports the theory of evolution by showing the continuity of life and the patterns of genetic change that have occurred over millions of years.
What is a positive selection vector?
A positive selection vector is a type of vector used in molecular biology that contains a gene conferring a specific trait or resistance to a selection agent, such as an antibiotic. This allows for the selection of only those cells that have successfully taken up the vector and integrated the gene.

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.
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."

Natural selectionwhat are some of the similarities and differences between artificial and natural selection?
Natural selection is more efficient ad more precise.

How can I use PyMOL to add hydrogens to a molecular structure?
To add hydrogens to a molecular structure using PyMOL, you can use the "hadd" command followed by the selection of the atoms you want to add hydrogens to. This command will automatically add hydrogens to the selected atoms in the molecular structure.
