What are the physical differences between people?

Answer 1

The list of physical differences between people, even among close family members, is immense. Although some people claim there are "look-alikes", there are relatively few instances of unrelated "likeness" among the billions of people alive today. Most of us share *some* characteristics with others, but we have enough dissimilar characteristics to make each person look unique.

Differences include:

• gene groupings must be different to have individual characteristics
• shade differences in eye color from the primary groups of blue, green, hazel, and brown
• shade differences in (natural) hair color from the primary groups of red, brown, black; even gray hair has differences
• Differences in heights and weights
• Differences in facial characteristics, including bone structure and features
• Differences in how fingers and toes look (short, stubby, long, slender, and so on)
• Differences in voice pitch, volume, intensity, richness - for example, compare the kind of voice we associate with radio and TV announcers to the majority of other people's voices who are not in radio or tv

For most humans, we share the same body systems and anatomical structures, but external characteristics and features differ.
