Are similar genes evidence of common ancestory?
If organisms have similar genes, then they are closely related.
Analogous structures are evidence of?
That different organisms are able to adapt to the same environment.
What does comparing organisms in the fossil record provide evidence for?
Comparing organisms in the fossil record providesevidence that organisms have changed over time
What evidence do these similar structures provide in support of evolution?
Comparative DNA samples from chimpanzees and humans show very well the concept of evolutionary common ancestry. Aside from that, the differences in DNA among organisms, especially at certain loci, show how long two, or more, organisms shared common ancestry.
What is indicated by a similarity in the pattern of embryological development exhibited by two different organism?
Such similarities are taken to be evidence of common ancestry.
Why is biochemical evidence of evolution considered to be indirect?
I do not know. I can look at shared biochemical pathways and see direct evidence of common ancestry with other organisms.
Are similar genes evidence of common ancestory?
If organisms have similar genes, then they are closely related.
Analogous structures are evidence of?
That different organisms are able to adapt to the same environment.
Are pharyngeal pouches and tails evidence of evolution?
It simply highly suggests that all organisms going through this developmental phase have common ancestry, thus are related on the tree of life.
If two organisms look very similar during their early stages of development this is evidence that the organisms are what?
Of common ancestry, though ontogeny does not recapitulate phylogeny, ontogeny, development, can create phylogeny.
The fact that all organisms have DNA as their genetic material is evidence that?
We all current life has a single common ancestor.
What evidence can be used to show that organisms share a common ancestor?
The DNA genetic code provides the best evidence of the common ancestry of life. Science has shown that there are many similarities between DNA sequences.
What is the Strong evidence for the common ancestry of all vertebrates is?
The strong evidence for the common ancestry of all vertebrates is THE SIMILARITY OF THEIR EMBRYOLOGICAL STAGES.
How is cytochrome c used biochemical evidence for evolution?
This electron shuttle is highly conserved across many species and jumps across taxa with little change in composition, thus providing evidence for the common ancestry of many organisms.
Is similarities an early development not evidence for evolution?
It does hint at common ancestry so it is "evidence" of evolution.
What provide evidence of common ancestry amongisms?
Simularities in DNA sequence
Why is DNA the weakest evidence of evolution?
Actually, it is the strongest evidence for evolution. Without one fossil we would know from the DNA evidence that evolution has occurred and is occurring. It is in the DNA of organisms that we see the strongest evidence for common ancestry. The products of those genes are sometimes highly conserved down the ages. Ribosomes, the workbenches on which proteins are made, differ hardly at at between you and pets.
