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.

Are lions and tigers evolved from a common ancestor cat like ancestor an example of micro evolution?
Tigers, Lions, Leopards, and Jaguars all belong to the genus Panthera, which are the cats that can roar. They probably all evolved from Viretailurus schaubi, but I don't know that for certain. The short answer to your question is that Lions and Tigers "probably" evolved from a common ancester. If you go back far enough in our evolutionary history, just about all animals share a common ancestor of some kind.
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.
Did humans evolve yes or no?
yes all animals evolved from a "common ancestor" and are still evolvingrelationships between all animals are summarised in "trees of life" that propose possible scenaris of evolution according to available scientific datas.You can visualise on them when divergence occured between animals from a common ancestor
What might this physiological similarity indicate about the evolutionary history of animals with backbones?
That all animals with backbones came from a common ancestor.
Why do scientists think that all animals come from a common ancestor?
All animals share the same genetic code, the same, or very similar biochemical pathways. All animals share physiological similarities from the cell to the epidermis. All animals share behavioral similarities. Answer All animals have similar traits. All have the same sorts of cells (no cell walls, centrioles, only small vacuoles if any) for example. This is evidence that all animals have a common ancestor. It fits the model of animal common ancestry, it fits the hypothesis. Since animals breed using DNA as a hereditary material, then their offspring are capable of inheriting traits. If the common ancestor of all of a group has a trait, then we can reasonably assume that all its descendents should inherit that trait. And that works in reverse too. If all members of a vast group share a character, then it is violently possible that they all inherited it from a common ancestor. Take the homology of limb bones of mammals to illustrate this principle in a tiny subset of mammals or the shell-possession of molluscs as another homology (yes, all molluscs have shells - even squid). It is easy to see that mammals should all have a common ancestor. It is (relatively) easy to hypothesise that all molluscs have a common ancestor. What about all animals, ALL animals? We have forgotten, by the way, the most modern way to examine relationships - DNA analysis. DNA analysis shall confirm that all animals form a clade, a monophyly, a single group arising from a common ancestor. That must be the greatest vindication of the animalian hypothesis for biologists - that DNA can confirm that all animals have a common ancestor.
Are elephants and crickets related?
Only in the sense that all animals share a common ancestor. Aside from that they are about as far apart ans two animals can get.
What features do all animals and plants cells have in common?
Because way in the past they are descended form a common ancestor.
The most recent common ancestor of all land plants was probably similar to modern-day members of which group?
Charophyte.
Which organisms have possible common ancestor?
All of them
The fact that all organisms have DNA as their genetic material is evidence that?
We all current life has a single common ancestor.
What was LU-CA?
LUCA stands for Last Universal Common Ancestor, the last organism that is the common ancestor of all life on Earth.
What are all the animals related to a cheetah?
The closest relatives of the cheetah are the cougar and the jaguarundi. All three species evolved from a common ancestor in North America.
