If someone postulates a scientific theory that
all life on earth has "common ancestors", then
in order to validate that you have to find them.
Note I am not demanding that, science is.
No, in order to validate the theory, you have to find various evidence
that would be expected from shared ancestry, and only from shared
ancestry. For example, humans share endogenous retroviruses
(nonfunctional strings of viral DNA) in our genome with other
primates, and these are most similar between humans and chimps, and
less similar between humans and, say, monkeys. There are, of course,
various transitional fossils linking humans with nonhuman apes and
apes with monkeys, but it is impossible to say whether any particular
fossil is that of a direct ancestor or merely an evolutionary "cousin"
of such an ancestor.
Since nothing in the idea of common descent with modification requires
that fossils exist at all, much less that the fossil record record
every population that ever existed, there is no implication in
evolutionary theory that every common ancestor be found in the fossil
record. Indeed, the most optimistic estimate of what the fossil
record contains are that about one-tenth of all the species that
existed left fossils, and surely most of those have not yet been
discovered or described.

Isn't dolphin DNA similar to human DNA?
Indeed it is. However, not as similar to human DNA as any primate DNA
would be. Dolphin DNA is much more similar to cow DNA (or any other
artiodactyl's) than to human DNA. Now why should that be?
Gee, I don't know. Could it be that something came
up out of the ocean, and then, later, before it
turned into a cow, went back to the ocean and
turned into a whale?
Basically, yes. Over many millions of years, aquatic animals
developed the ability to live on land. Many millions of years later,
some of their descendents gradually adapted to living in water. The
evidence is quite clear that this happened.

(Now say that with a straight face.)

Dolphins are marine mammals with many similarities to humans. And in
fact, they may have more in common with us than we think.

Thirteen of 22 dolphin chromosomes are identical to human chromosomes,
according to researchers at Texas A&M University. And the nine
remaining chromosomes were found to be combinations or rearrangements
of their human counterparts.

The dolphin's anatomy is strikingly similar to our own, in spite of
the obvious differences. Bones of the hands and feet are almost
identical, only theirs are housed in their fins. Dolphins also
experience emotions in the same way that humans do. They can feel a
wide spectrum of emotions, from joy and exuberance to sadness and
pain.

It has also been discovered that dolphins have healing abilities and
are able to connect with humans unlike any other animal.
