The second of Darwin's three principles is that:
AMore offspring are born than survive
BEvery offspring born will survive
CResources are always unlimited
DOffspring are identical to parents
Answer & Solution
Correct answer: A. More offspring are born than survive
1. Selection requires that not everyone can make it.
2. More offspring are produced than are able to survive, so resources for survival and reproduction are limited.
3. That shortfall is what makes the competition consequential.
4. If every offspring survived, no trait could be favoured over another.
