RC Question 16 Explanation, by LSATHacks

DISCUSSION: Lamarck’s hypothesis is described in lines 1-6. You should reread those lines. He said that the way a parents uses an organ will affect how the child’s organ works. 

For example: I start running marathons, and because of that my future children are born as good endurance runners.

___________

1. This doesn’t say whether a parent’s usage of antlers affects the child’s antlers.
2. CORRECT. An animal uses an organ in one way, and that affects the organs of future animals. 
3. This has nothing to do with potatoes transmitting traits to future potatoes.
4. This doesn’t tell us whether the children of those lions tend to be worse at directions, even if they’re raised in the wild.
5. This is very tempting. Can you think of another reason why wild dogs might be more wild? The dogs bred for hunting are likely being raised by humans, and this probably makes them less wild. It may have nothing to do with genetics.
