What makes peoples faces different?

Question

I cant work it out, everyone has a nose, two eyes, and a mouth, how is it possible for there to be millions of people with different faces. Its the same with voices, everyones voice sounds different but how. Think about it, it doesnt make sense...

What im trying to say it that fair enough we know how we are made differently, but if everyone has two eyes, a nose, and a mouth, how do we see people differently, i dont understand how there can be millions of different faces using simply a nose, eyes and a mouth.

Answer 1

It seems to be the case that humans do show a lot more variation in their physical appearance than other animals (for example sheep look pretty much alike to us). One reason for this could be that in ancient times, tribes, for various linguistic, social and cultural reasons, tended not to interbreed much, allowing natural selection to favour different skin tones and facial features.

In addition the human mind appears to be highly 'tuned' to recognise faces, and slight difference in facial features appear exaggerated to us.

Answer 2

We love difference!!!

and we are all human and we are unique in terms of our family, our environment, and especially our genetic make up.

We have eyes that can distinguish very slight differences between people's faces. There is a difference and we have eyes that can see that difference.

When you think about identical twins, you will see they look like same, you mostly can not distinguish them. They are identical because they have same genetic make up, and same mother and father, and most probably they have grown in the similar environment.

There are genes controlling variance in formation of our face and this mechanism has a great probability number that every time every people get different face, and voices.

Answer 3

Wow... good question! I'm gonna give you a star! We all know that genetics gives us our features, but I don't think that was the answer you were looking for! The whole concept of how we can all look so different is intruiging! I hate it when people answer so seriously to question which is meant to make you ponder!

Answer 4

Genetics.

Answer 5

Lets put it this way, we are all different because we are the result of different "combinations"...we're not all born from the same parents, and if we are, the punnet square can explain why we can look SIMILAR but not exaclty the same

Answer 6

Genetics. It's in the genes. Also, not everyone is born of the same parents.

Answer 7

Try drawing someones face who you know well. you will soon realise that the slightest discrepency in one single detail will alter the overall view of that persons face. which is probably why an artists skill is not easy to master.

Answer 8

Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and functioning of living organisms. All living things contain DNA genomes. A possible exception is a group of viruses that have RNA genomes, but viruses are not normally considered living organisms. The main role of DNA in the cell is the long-term storage of information. The genome is often compared to a set of blueprints, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the expression of genetic information.

In eukaryotes such as animals and plants, DNA is stored inside the cell nucleus, while in prokaryotes such as bacteria, the DNA is in the cell's cytoplasm. Unlike enzymes, DNA does not participate directly in most of the biochemical reactions it controls; rather, various enzymes act on DNA and copy its information into either more DNA, in DNA replication, or transcribe and translate it into protein. In chromosomes, chromatin proteins such as histones compact and organize DNA, which helps control its interactions with other proteins in the nucleus.

DNA is a long polymer of simple units called nucleotides, which are held together by a backbone made of sugars and phosphate groups. This backbone carries four types of molecules called bases, and it is the sequence of these four bases that encodes information. The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code. To read the genetic code, cells make a copy of a stretch of DNA in the nucleic acid RNA. Some RNA copies are used to direct protein biosynthesis, but others are used directly as parts of ribosomes or spliceosomes.

Answer 9

That's why we are UNIQUE, like snowflakes, not two are alike.
Like Finger Prints, are all unique. Even Identical Twins have differences. It would be terribly difficult for 'nature' to make them all alike.

Answer 10

Look at all natures creations they are all slightly different...there is supposed to be a similar looking person to yourself (the opposite sex) somewhere in the world and they reckon it is your perfect partner
could be an old wives tail or something though
