Which is the best description of how the fossil record provides evidence of common ancestry?

Put simply, it doesn't. There really is no other reason, any archaeologist, paleontologist, geologist, or other professional in a field of artifact study will tell you that there is no "line" of creatures leading up to today's animals. For example humanoid skeletons where found conspicuously at the beginning of the Cambrian period and at no time before then, the only explanation for this is that an unaccounted for variable such as a "supernatural force" was present and not noticed

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.
What are five types of homologies that provide evidence of common ancestry?
limbs wings legs arms and flippers
What is the strong evidence of common ancestry between the organism that share them?
Simularities in DNA sequence
The hominid fossil has the same number of bones in its hand as a gorilla. what type of evidence for evolution does this represent?
That evidence is homologous. Shared common ancestry. In this case you could trace this homology back as far as the common ancestor of gorillas and hominid fossils, or as far back as the emergence of all tetrapods.
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.
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.
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.
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
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.
What evidence supports the common ancestry of dinosaurs?
Many of their genes are the same.
Are similar genes evidence of common ancestory?
If organisms have similar genes, then they are closely related.
Which of these might be used to determine common ancestry of two different species of plants?
fossil evidence :)
What are five types of homologies that provide evidence of common ancestry?
limbs wings legs arms and flippers
Analogous structures are evidence of?
That different organisms are able to adapt to the same environment.
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.
Which of these might be used to determine common ancestry of two different species of animals?
Fossil evidence
