Answer 1

Evolution does not design. We (life) are a collection of random mistakes that made our ancestors a slight amount more likely to breed and produce viable offspring.

As for sweat, when we get stressed our sympathetic nervous system causes psychological changes like increased heart rate and sweating as part of “fight or flight” response. Your body sees stress like a light switch. On: increased heart rate and sweating. It does not differentiate climbing, lions, finals, boss yelling, or public speaking.
