200
A tentative explanation
What is "hypothesis"?
200
He proposed the idea of evolution through "Acquired Traits".
Who was "LaMarck"?
200

300
The process of repeating the experiment over and over
What is "Validation"
300
Evolution in many directions to fill vacant niches.

400
The pattern of evolution that results in similar traits found in very different groups, such as the wing of a penguin and the fin of a dolphin

500
A statement that has been supported by all the available evidence.

500
The result of overproduction of offspring and limited resources?
