Answer:

Option A is correct (Alfred Wallace).

Explanation:

Option A is correct (Alfred Wallace).

According to the evolution theory all living species are evolved from a simple life source with the passage of time.

Points of natural selection:

  • Genetic variation are passed from generation to generation but environment can cause variations too.
  • Individuals in species have gene variation which is due to random mutation
  • Those who can not adopt to environment can not have their genes pass to next generation.
  • Natural Selection is also called as "Survival of the fittest".

Answer: Option A.

Alfred Wallace.

Explanation:

Alfred Russell Wallace was an English naturalist born in January 1823. He independently proposed theory of evolution by natural selection. His scientific ideas encouraged Charles Darwin to work together with him and they both published their scientific ideas in 1858.

Wallace thought that an inferior variety can coexist with another superior variety in the environment, until deteriotion forced the inferior variety to be extinct from the environment and this is totally different from Darwin's view which said that individual with heritable trait are better suited in their environment.

Develop a hypothesis to explain why you think eurypterids developed legs even though they lived on the ocean floor.
expeople1 [14]

I think that since it lives on the ocean floor, at the deepest of the ocean. So anyway, the fin on the Eurypterids is still necessary but not that much, since they live on the ocean floor. Their movements mostly on the ocean floor. So fin would not help them "stick" to the floor. Also there are still gravity acts on the Eurypterids and the feet would help them move faster. Hope this helps.
