How could 2 people who are NOT related, look so much alike ( NATURALLY) ?

Question

I heard that look alikes share an ancestor but just do not know it. Does anyone know if this is true and if not, does anyone know how is it possible for 2 people, who are not related, too look so much alike?

Answer 1

A couple of simple mathematical exercises will prove what geneticists have proven through DNA evidence: that populations that have been in a given area for many, many generations are very closely related indeed, sharing many of the same ancestors.

The exercises: First, divide the current U.S. population by six. That, by sheer coincidence, will tell you roughly what the population was six generations ago: that is, a lot less than now, yet we each have two parents, four grandparents, eight great-grandparents, sixteen great great grandparents (usually shared, of course, with a number of brothers and sisters!)

But how do you reconcile this ever-increasing number of ancestors in each generatiion back, with the fact that, the further you go back, the LESS people there were?

The only explanation is that a lot of allegedly unrelated people have to have shared a lot of ancestors! Isolated populations-- and most U.S. populations were quite isolated until a a couple or three generations ago-- marry close cousins and keep doing it in every generation, whether or not they are aware of being related. This increasing tendency of an isolated population to unwittingly or wittingly marry relatives is aggravated by a genomically-proven high incidence of illegitimate births.

You know how it goes: The ladies' man in a small town impregnates 20 per cent of the women, and equally attractive and virile descendents of his proceed to impregnate another generations of women who, unknown to them, are their half-sisters or cousins! That perennial favorite, incest-- taboo linkings between cousins and people even more closely related-- is a factor of indeterminate dimensions in bringing us all closer together.

So no wonder so many people look alike! The wonder is that there are not more genetically-based disorders owing to a declining gene pool. Thank God for recent increasing immigation and interracial marriages, which tend to expand the national gene pool.

(For a perhaps apocryphal example of human degeneracy and moral depravity, It is said, truthfully or not, that Hitler for a time kept his own niece as his mistress, but, if true, I never learned if he iimpregnated her. Hitler, foremost apostle of eugenics and racial purity, is said to have come from an inbred little community in Austria where cousins often married and everybody was fanatical about keeping out outsiders.)

Visitors to the community have said that the people tended to be surly, stubborn and strong-willed, and to be very much like Hitler in appearance. Not surprising, as he was a very ordinary-looking man except for his striking haircut and mustache.

Never fear: if the world ever needs another Fuhrer, perhaps Hitler's genome is alive and flourishing! There were so many Hitler look-alikes in Nazi Germany that it wasn't even funny. The number was so remarkable that he is said to have trained several of them to rant and rave in public "Hitler appearances" while he was occupied with other things. One of them, Adolf Kreuger, was responsible for numerous "Hitler sightings" after the war, and somebody still occasionally sights the 120-year-old Furher and he shows up in a grocery story magazine.

He must have had a very virile and insane ancestor, hence probably an abundance of collateral descendants ready to rave their way back into power someday.

Answer 2

It is really weird but it is true. I actually met my look alike but I didn't think we looked that much alike but people would sit down and hold a conversation with her and then realize that it wasn't me. I also had a few people tell me I was just over there and how did I get here so quickly. I would laugh and point out the other girl and tell them that's because it wasn't me silly. She was very pretty so I definitely was insulted. As far as the being related part I'm positive she is not related to me by at least past the 8th cousin or so maybe. We never found any connection to our families it was just an coincidence that we looked so much a like.

Answer 3

I don't have a scientific reason, but it is possible for 2 unrelated people to look alike. I know there was a girl in the city where I grew up that looked just like me. We were also the same age. And even more stranger, I know people of 2 different races that look the same. Crazy.

Answer 4

People Look Alike

Answer 5

Well, everyone in the world (including animals other than humans- even the ones that are always still and have an almost-alien biology, like corals and starfish, but not plants) is actually related as we all have a common ancestor, unless there are aliens, demons, angels or some other things like genies that hold a separate genome from humans and animals. Both demons and angels are often depicted as almost human looking, and so are genies, but for all we know, they could look like animals, plants, completely weird beings, or even no physical form.

We also do not know how aliens would look like.

Answer 6

Well you see if we go back far enough. , all of us share an ancestor. Why wouldn't it be possible? There are only a few face types out there and there's only so many variations you can have, so why would it not be possible for two people to look alike? I've seen heaps of unrelated people who look like me.

Answer 7

Are you ignorant? Researchers use more than "They look alike" to determine closer related species. Light bulbs take many weird shapes, and they have a function - as a load - to convert electrical energy in to light energy. They have no relation to eggs. Our solar systems didn't "evolve" from one atom. You don't even understand what "evolve" means. There is no "solar system" evolution. You've killed your own arguement to say that our solar system evolved from an atom, which don't replicate or reproduce. Your logic fails to meet the law of conservation of mass and energy. Your airplane argument destroys your argument as well because airplanes don't even look a thing like birds, they are mechanical and man-made. They were inspired by flying animals. The only changes that can be made to airplanes are man-made and meant to suit its purpose. Airplanes - again - can not replicate or reproduce either, only living organisms do that. Their function is to fly, yes, but how they achieve this is much different then a bird does. No really, what's your REAL question? I'm not even sure I understood this question.

Answer 8

I'm sure you heard that saying that you will always have someone that looks just like you.
It's true in a matter of fact it's been know that there are people all over the world that may look like someone.
in other words there can be more then one person that look alike but not be related.

For real tho, we all is related rather anyone will admits it.

Answer 9

It is amazing when you see that and I have. Yet, they are never identical when you look at them up close. I think there's so many people in the world you have to have some of them look almost alike. I've had people say I look like one particular person who lives about 10 miles from me and they call me that name; however, when I met the person, I could not see the resemblance myself.

Answer 10

I think it's got to be possible. With all the people in the world, remembering that although there's variation on how we look, most people's faces come down to the same basic structure, i.e. ears, nose, mouth ets. It would be a miracle of nobody looked a bit the same even without being related!
