The more similar the two groups are, the most recent the common ancestor probably is.

What is the ancestor of eukaryotes?
Archaebacteria is probably more likely to be the ancestor of eukaryotes because of certain similarities, such as the ribosome of the two groups being much more similar to each other than the ribosomes of bacteria.
What is it called when the environment affects which organisms will live or die?
Probably natural selection. The environment is the selector of organisms.
Colonial organisms probably evolved into what?
Animals, plants, and fungi.
Multicellular eukaryotes that are usually mobile and obtain food from other organisms probably belong to which kingdom?
They are probably animals.
What common ancestor does all life share?
The last universal common ancestor (or LUCA) for all known life would have been some single celled organism similar to prokaryotes. It might have been an RNA or DNA based organism, but it would have used more or less the same genetic code as all modern organisms (with a few minor variations) today. It will probably have lacked a true cellular nucleus, and many of the organelles that modern organisms have, but it would still have used ATP as a key factor in its metabolism. Note that, like with all Most Recent Common Ancestors for any group, it is not necessary that a single species of organism is the sole ancestor for all modern life. It may well be possible that different species contributed to modern life (see also: multiple origins hypotheses). There will be one single ancestor common to any specific set of traits in all the diverging lineages, but, depending on the set of traits examined, they may lead to different origins. Compare, for instance, to mt-DNA Eve and Y-chromosome Adam: there is one most recent common ancestor for all surviving variations of mitochondrial DNA via matrilineal descent, but there is a different ancestor, living in a different era, for all variant Y-chromosomes surviving through patrilinial descent. It is, however, likely that there was, at some time, indeed one single species or closely linked collection of species of organisms from which all modern life descends. Also note that LUCA concerns only the most recent of such ancestral organisms: it itself would have had ancestors, and shared ancestors with other lineages existing at the time.
The fundamental likeness of body structure in all vertebrates indicates that these organisms probably originate from?
The body structure in all vertebrates indicated that these organisms originated from Precambrian times. This has to due with having a back bone.
Is it true that the more similar two organisms are the more distant their common ancestor probably is?
yes it is true
What did taxonomists learn from Darwin's theory of evolution?
That all organisms on earth are related and rose from a probably universal common ancestor. That all organisms can be placed on the " tree of life " in nested hierarchies of ever growing ( for the most part ) complexity.
Humans and gorillas have one different amino acid in their hemoglobin sequence. What does this say about the evolution of these two species?
Answer this question… They probably have a recent common ancestor.
The number and location of bones of many fossil vertebrates are similar to those in living vertebrates Most biologists would probably explain this fact on the basis of a the needs of the organisms?
No, b) a common ancestor.
What was the common ancestor of all animals was probably?
The last common ancestor of all animals was likely an organism not unlike modern-day protists.A single celled animal, not a plant found in the deepest oceans.
What Does This Say About Evolution Of These Two Species?
They probably have a recent common ancestor
How can 2 organisms have the same ancestor?
It's a complicated answer. Every living organism on the planet can trace its roots all the way back to one organism -primitive precambrian bacteria. A colony of bacteria was probably separated into two colonies which were then isolated. Both groups were probably faced with different environmental challenges. Only the bacteria with the adaptations that kept them from dying survived long enough to split themselves and reproduce. That's how evolution works. Every time a group of organisms is isolated and each one is relocated in has different environmental factors, only the ones with the right stuff will make it. Eventually the separate groups will evolve into completely different species as their helpful adaptations are amplified through the generations, but the original group from which they both came is their common ancestor. I'm not sure if I explained that clearly enough, but that is how different organisms share a common ancestor.
What do protists lack what probably makes them so diverse?
a common ancestorA common ancestor is what protest lack. This is what makes them so diverse.
What are you to your aunts mother in law?
You could be their grandchild. Or you may not be related at all, as not sharing a common ancestor.
Was job a desendant of Jesus Christ?
No. Probably not an ancestor either as he does not appear in either genealogy.
What does this say about the evolution of these two species?
