Question

which observations did darwin make? select the three correct statements. each species seems suited for its particular environment. a population has more individuals than can be supported by the environment. each individual frequently and continuously uses the necessary organs. heritable variations exist in each population. all organisms share similar features. the population size suits the resources of the environment.

Explanation:

Darwin observed that species are adapted to their environments, populations have more individuals than resources can support (over - production), and there are heritable variations within populations. These are key aspects of his theory of evolution by natural selection. The idea of continuous use of organs is Lamarckian, not Darwinian. While organisms may share some features, it's not one of Darwin's main observations related to his theory. And the population size suiting resources is not a main Darwinian observation as populations tend to over - produce.

Answer:

• Each species seems suited for its particular environment.
• A population has more individuals than can be supported by the environment.
• Heritable variations exist in each population.
