Question

1. according to darwin, what advantage did a longer neck give a giraffe? 4. which theory do you think makes more sense and why? (think about it: if you lift weights and get big muscles, will your children be born with big muscles?)

Explanation:

For question 3, according to Darwin's theory of natural - selection, a longer neck gave giraffes access to higher leaves on trees, which were out of reach for other herbivores, thus providing more food resources. For question 4, Darwin's theory of natural selection makes more sense. Traits acquired during an organism's lifetime, like big muscles from weight - lifting, are not heritable. Only genetic variations that are present in the germ cells are passed on to offspring.

Answer:

1. It gave access to higher leaves, providing more food.
2. Darwin's theory of natural selection makes more sense because acquired traits (like big muscles from weight - lifting) are not heritable; only genetic variations in germ cells are passed on.
