Take the electron shuttle of the electron transfer chain in eukaryotes, cytochrome C. This highly conserved protein structure and its biochemical action is seen in many prokaryotes across many taxa and diverges in genetic instructions and form as would be expected in organisms of common ancestry.
Biochemistry is concerned with chemical substances and processes that occur within plants, animals and microorganisms. All life has prominent similarities at a molecular level. Organisms have basically the same:
they use fossils to determine it -Chasity Kaplan put this answer
The biochemical commonality is DNA.
In every way.
Because due to Darwins theory of evolution, fossils lead to adaptations over time therefor giving us reason to find evolution within human beings and animals.
Fossils are not used to oppose the theory of evolution. They acutually support it in every way. So far not one fossil has been found that is not exactly where you would expect it to be if evolution were true. As we dig deeper we go further back in time and see by piecing fossils together how organisms evolved over time. Although we don't need fossils to support the fact that evolution is happening, it's a nice bonus to have in support of the theory.
The fact that sheep insulin can be substituted for human insulin is an example of evidence of evolution based on comparative biochemistry. Insulin is a peptide hormone.
Relative and absolute dating of the rocks and the fossils near it (geology and archaeology), as well as chemical components of various surrounding areas are consistent in explaining the diversity of life as explained by theory of evolution. Evolution is also consistent with embryology, genetics, comparative physiology, biochemistry, and more. See the related link below for more details.
It is generally thought to support the Theory of Evolution.
The better question would be; what biological sciences DO NOT support Darwin's theory of evolution by natural selection. Evolution is the backbone of biology and the theory that explains much about evolution is the bedrock on which all biology is built, regardless of the apparent absence in some disciplines of biology. It is no longer just Darwin's theory as many disciplines not formed then, and some extant then, have added to and refined the theory. Genetics Molecular cell biology. Evolutionary developmental biology. Biochemistry. Geology. Paleontology. Population generics. Botany. Evolutionary biology. And the list can go on. Google, disciplines in biology, wiki.
Intermediate forms are predicted by evolutionary science in several ways. Their presence supports the theory of evolution.
The theory predicts that evolution will happen and in certain ways. The observed evolution makes this prediction correct. It also defines evolution as happening, and as such is perfect evidence in support of it.
I do not so much " believe it " as I an convinced by the myriad lines of converging evidences that support the theory of evolution by natural selection. talkorigins.org
A biochemistry major is not a pure biology discipline. Biochemistry includes chemistry and the various disciplines in chemistry which also support biological theory.
In every way.
There is strong support for the theory of evolution due to fossils that have been found by archeologists. The fossil records show evidence of evolution over billions of years.
There is no proven theory of evolution only the physical evidence of what Chuck Norris has allowed to live.
evolution theory
Prove is a term used in math. Comparative biochemistry supports with many lines of converging evidence the theory of evolution by natural selection. For a brief example consider cytochrome C, the electron shuttle that shuttles electrons between the I and II complex of the electron transport chain. This biochemical process is highly conserved in many types of organisms, being remarkably the same process from organism to organism, but showing the expected slight genetic variation that can be tracked down the taxa to support the common ancestry of evolution.
