An adult human skeleton contains 206 bones, so the statement "The human skeleton is made up of less than 100 bones" is false.

1) Relevant knowledge points and concepts
- Typical adult human skeleton: 206 named bones (skull, vertebral column, ribs, limbs, etc.).
- Infants are born with about 270 bones; many fuse during growth (for example, skull and pelvic bones), reducing the count to the adult total.
- Comparison of quantities determines truth of a "less than" statement.

2) Step-by-step reasoning
- Identify the factual count for an adult: 206 bones.
- Compare this number to 100 to evaluate the claim "less than 100."
- If 206 < 100, the claim would be true; if 206 ≥ 100, the claim is false.

3) Intermediate calculation steps
- Adult bone count = 206
- Compare: 206 < 100? No.
- Alternatively: 206 − 100 = 106, which is a positive number showing 206 exceeds 100 by 106 bones.

4) Why the correct answer is correct
Because the adult human skeleton has 206 bones, the numerical comparison directly contradicts "less than 100." The factual anatomical count therefore makes the statement false. The additional note about infants (≈270 bones) reinforces that even at birth the count is well above 100.

5) Why the other option is incorrect
- "True" would assert that the skeleton has fewer than 100 bones. Given the established, well-documented adult total of 206 bones (and the infant total of ~270), that assertion is incorrect.

6) Conclusion confirming final answer
The correct evaluation of the statement "The human skeleton is made up of less than 100 bones" is False, which matches the provided answer: False.
