Since Danwin's time, scientists have studied genes and gene function in a wide variety of organisms What type of evidence for evolution is provided by data from these studies? A. Inconclusive evidence, because the genes of ancient species cannot be studied B. Inconclusive evidence, because scientists have not yet related genes to physical traits C. Weak evidence, because evolution involves changes only to body shape and body functions D. Very strong evidence because of homologous genes and the overwhelming similarities in the genetic code

## Step 1<br />The question is asking about the type of evidence for evolution that is provided by the study of genes and their functions in various organisms. The options provided are:<br /><br />A. Inconclusive evidence, because the genes of ancient species cannot be studied<br />B. Inconclusive evidence, because scientists have not yet related genes to physical traits<br />C. Weak evidence, because evolution involves changes only to body shape and body functions<br />D. Very strong evidence because of homologous genes and the overwhelming similarities in the genetic code<br /><br />## Step 2<br />Option A suggests that the evidence is inconclusive because the genes of ancient species cannot be studied. This is not accurate because while it is true that the genes of ancient species cannot be studied directly, scientists can study the genes of modern organisms to infer the genes of ancient species.<br /><br />## Step 3<br />Option B suggests that the evidence is inconclusive because scientists have not yet related genes to physical traits. This is also not accurate because scientists have indeed related genes to physical traits, which is a fundamental aspect of genetics and evolutionary biology.<br /><br />## Step 4<br />Option C suggests that the evidence is weak because evolution involves changes only to body shape and body functions. This is not accurate because evolution involves changes at the genetic level, which can affect body shape and body functions.<br /><br />## Step 5<br />Option D suggests that the evidence is very strong because of homologous genes and the overwhelming similarities in the genetic code. This is accurate because homologous genes are genes that are similar in different species because they have evolved from a common ancestor. The overwhelming similarities in the genetic code across different species provide strong evidence for evolution.
