HEy guys! THX 4 ur help!!

Answer 1

In 1831 the Beagle left on a five-year voyage to South American and Australian waters. During this time Darwin observed and studied in many remote regions of the world. He collected great numbers of plant and animal specimens. From detailed notes of his observations he began to develop the theory that was to make him famous. When he returned to England Darwin began studying and investigating nature. In 1844 Darwin began to compile his greatest contribution, Origin of Species, in which he proposed his theory of natural selection. All life, he said, is a continuous struggle in which only the fittest can survive. In this period Darwin discovered that the idea of natural selection was not exclusively his. Alfred Russel Wallace ( 1823-1913 ), a young naturalist, had developed similar ideas in an essay called "On the Tendency of Varieties to Depart Independently from the Original Type." Wallace sent this paper to Darwin for an opinion. Darwin took Wallace's manuscript to a friend, Sir Charles Lyell, who decided that both Wallace's and Darwin's ideas should be presented at the same time. On July 1,1858, both papers were read at a meeting of the Linnaean Society of London.

Answer 2

Darwin investigated the transmutation of species and conceived his theory of natural selection in 1838. His 1859 book On the Origin of Species established evolution by common descent as the dominant scientific explanation of diversification in nature.
this is from wikipedia but i've checked with other sources for the accuracy and it matches
hope this helps:)

Answer 3

He didn't discover evolution, he formed a theory of evolution. He basically started the theory that mutations in animals and humans created better odds of survival and therefore the offspring lived and had babies that had the same mutations. Through these mutations, the species evolved and adapted easier to climate and environmental changes. I think it was about 150 years ago, but I'm not sure.

Answer 4

Darwin did not discover evolution. He made up a hypothesis of it. He theorized evolution.
