Hutton helped scientists realize Earth is millions of years old and the processes that changed Earth in the past are the same processes that operate in the present.
In 1795, he published a detailed hypothesis about the geological forces that have shaped Earth.
Lyell stressed that scientists must explain past events in terms of processes they can actually observe, since processes that shaped the Earth in the past still occur in the present.
Lyell's book, Principles of Geology, explained how awesome geological features could be built up or torn down over long periods of time.
Conceived the theory of natural selection. Natural selection is when organisms adapted well to their enviroment survive better and reproduce more than those who are not.
Helped Charles Darwin with his theory, eventually having both of their theories joint together.
Invented the theory of evolution.
Proposed the theory in his book, On the Origin of Species, written in 1859.
He was a taxonomist. He developed a way to organize and name species, which we still use to this day.
The system he created includes domain, kingdom, phylum, class, order, family, genus, and species.
Malthus reasoned that if human population grew unchecked, there wouldn't be enough space or materials for them all.
In 1798, Mathllus publishd a book noting how babies were being born faster than people were dying.
Lamarck proposed that all organisms have an already aquired tendency to strive to perfecion and complexity. As result, they are always changing.
Lamarck theorized that the disuse of organs led to the organism losing them over time. Over time, this led to changes in species.
