What animals did the grant study in galapagos island?
Galapagos finches did the grant study in Galapagos island.
Galapagos finches is a piece of evidence supporting the theory of evolution.
Darwin's finches comprise a group of 15 species endemic to the Galápagos (14 species) and Cocos (1 species) Islands in the Pacific Ocean. The group is monophyletic and originated from an ancestral species that reached the Galápagos Archipelago from Central or South America.
What did he observe?
During the survey voyage of HMS Beagle, Darwin was unaware of the significance of the birds of the Galapagos. He had learned how to preserve bird specimen while at the University of Edinbugh and and had been keen on shooting, but he had no expert in ornithology and by this stage of the voyage concentrated mainly on geology. Nonetheless, these birds were to play an important part in the inception of Darwin’s theory of evolution by natural selection.
What was the brief goal of their studies?
All of Darwin's observations and insights, plus reading of increasing population growth and demand for limited resources, brought him to his theory of natural selection. Briefly, this means that individuals better adapted to their environment survive and increase in number through reproduction.
What did they conclude?
Conclusion:
Charles Darwin deserves primary credit for the theory of evolution. He developed existing ideas about descent with modification while providing a large body of evidence in support of them, and he was the first person to perceive thatnatural selection is the primary force behind evolution.

Dependent and Independent variables are regarded as variables in mathematical and statistical modeling and of course in some other aspects.
The independent variable is this case is the amount of salt.
- In this kind of scenario, one can think of independent and dependent variables in terms of cause and effect.
- An independent variable is the variable we assume to be the cause, while a dependent variable is assumed as the effect.
- Therefore, with this case, the amount of salt would cause a decrease in the number of plants.
- While the effect of increasing the amount of salt would be seen in the number of plants.

<span>Organelles are needed for all cells to sustain life. Cell theory states:
-that all living things are made of cells
-all cells camef rom preexisting cells
-and all cells are the basic structure of life.
The function or organelles is that it carries the little organs which are needed for specific functions in the body.</span>
