Voyage on the H.M.S Beagle
In 1831, Charles Darwin set sail aboard the HMS Beagle, where he would spend more than 3 years of the 5 year trip observing and collecting specimens of plants, animals, rocks and fossils which were used to form his theory of evolution by natural selection (wilkin, 2019). This theory states that a species whose traits compliment its environment will reproduce more than those who traits don't. -
Darwin's Finches
While visiting the Galapagos Islands, Darwin observed the characteristics of the various finches that were found spread throughout the island. Later, he determined that at least 13 different species of finches had evolved from a single ancestor, which led to his theory of adaptive radiation (evolution). The reason for these changes are in regards to the species environment and what resources are available in which they must adapt and strive to survive. -
The Origin of Species
Once Charles Darwin had return from his 5 year long voyage, he published the well known book called "The Origin of Species". It conveyed his observations and theories about evolution and natural selection. "His book laid the groundwork for modern botany, cellular biology, and genetics"(charles, 2009).

The Phototropism Experiment
Plants play a major role in Earths environment and they require light to survive. Charles Darwin had conducted some of the earliest phototropism experiments which he conducted how a coleoptile would reach to directional positioned light source and concluded that the plant would bend and grow towards the light (phototropism).
