LAMARCH WRONGLY ARGUED THAT INDIVIDUALS CAN PASS ON (ACQUIRED OR INHERITED) TRAITS TO THEIR OFFSPRING |
ACQUIRED |
|
|
WHICH THEORY EXPLAINS THAT INDIVIDUALS WITH THE MOST HELPFUL VARIATIONS ARE MORE LIKELY TO SURVIVE AND REPRODUCE IN THEIR ENVIRONMENTS? |

|
EXPLAIN THE IMPORTANCE OF VARIATION OF TRAITS IN A POPULATION. |
THE MORE VARIATION THE BETTER CHANCE OF SURVIVING ENVIRONMENTAL CHANGE. |
