Does every human have a unique face?

The amazing variety of human faces – far greater than that of most other animals – is the result of evolutionary pressure to make each of us unique and easily recognizable, according to a new study by University of California, Berkeley, scientists.

Are humans infinite?

No we are not actually infinite. An actual infinity has properties you would not necessarily like, such as being equivalent (in a specific sense) with a proper subset of itself. What may be plausible is that we are potentially infinite: finite but with no upper bound on certain properties.

Why don’t we all look exactly the same?

Your genes play a big role in making you who you are. The color of your hair, the color of your eyes, and the dimples on your cheeks are all controlled in part by your genes. But brothers and sisters don’t look exactly alike because everyone (including parents) actually has two copies of most of their genes.

Are there infinite worlds?

And on that Earth was another you? For at least a hundred years, physicists, cosmologists, and philosophers have pondered the possibility that Earth and the people on it are far from unique. In fact, scientists today believe it’s very likely there are infinite versions of our planet and ourselves out there somewhere.

Is there a finite number of possible human faces?

Thus there is necessarily a finite number of possible anythings. Not all possible arrangements of matter will count as a human face, however, so an even smaller finite number will express the limit of how many human faces there can be.

Why do humans have so many different faces?

Human faces are so variable because we evolved to look unique. The amazing variety of human faces – far greater than that of most other animals – is the result of evolutionary pressure to make each of us unique and easily recognizable, according to a new study by University of California, Berkeley, scientists.

Is there an upper limit to the size of a face?

Nothing too large will count, and neither will something too small. It is the former point that matters to us, though: if there is an upper limit on the size a human face, then there is an upper limit on the amount of matter that there can be in a human face.

Why do we recognize faces so well?

There is a known neurological reason for this affinity for human faces: A dedicated part of the visual association cortex, the fusiform face area (FFA), specializes in recognizing and remembering them. Damage to the right FFA — from a stroke, for example — may cause a condition known as prosopagnosia, which is an inability to recognize faces.
