Plants and people have same protein, according to report in Biology News Net 9 April 2007. Scientists at Scripps Institute have found that humans and plants have a common biochemical pathway that helps them resist bacterial infection. A human protein called Nod1 is activated by another protein named SGT1. In plants SGT1 activates a group of proteins named Resistance proteins, which have a similar structure and function to the protein family that includes Nod1. SGT1 is also found in yeasts and mammals. Richard Ulevitch from the laboratory that conducted the study suggested that some protein regulatory pathways exist in plants and humans "simply because they do the same thing in much the same way". He commented: "In reality, there are only so many ways to accomplish related biological responses."

Editorial Comment It is good to see mainstream biologists admitting what is basically common sense, rather than making up some contrived evolutionary story. For many years creationists have been pointing out that finding the same protein in two different living things only proves that they both need it for a similar purpose, and this does not prove any evolutionary connection between the two. Finding the same kind of protein in two living things is like finding an axle in both a wheel barrow and a car. It does not prove one machine turned into another, but it does show that whoever built the machines knew what was needed to make them work and intelligently put similar bits in. The same applies to living things. The Creator of all living things made them as separate, unique combinations of often common and appropriate components. (Ref. biochemistry, immunity, design)
