Part One Content: Learning a New Lesson

Observe our differences

Tip: Observe the similarities and differences in appearance within the group. Choose 1 to 2 facial features, observe them carefully, and draw what each person looks like.

Through observation and comparison, we found:

The same facial features may or may not be the same between people. For example, among two people, one has double eyelids and the other has single eyelids.

Are our looks unique?

Which of our physical features are the same and which are different? If these two facial features are combined, how many different types of people will there be?

And so on:

Three facial features will produce eight different looks; four facial features will produce 16 different looks; five combinations will produce 32 different looks...

After long-term research, some experts have discovered that when skin color is inherited, people have no choice. It always follows the natural law of "multiply and average" and you will be branded with the "synthetic" color of your parents.

During skin development, although the epidermis, dermis and matrix are all growing together, the soft subcutaneous tissue grows faster than the hard epidermis, which exerts a steady upward pressure on the epidermis, forcing the slower-growing epidermis to shrink.
