The theory of Natural Selection.
Charles Darwin
Context
Darwin lived in the 19th century, during a time when the prevailing belief
Voyage
Darwin embarked on a five year voyage aboard the HMS Beagle from 1831 to 1836, traveling to various regions including the
Galapagos Island
Chile, Cape verde, an island and Australia
Evidence
Darwin observed variations among species in different environments, such as the different shapes and sizes of finches' beaks on the Galapagos Islands. He also studied fossils and the similarity of species in different regions.
Alfred Russel Wallace:
Context
Wallace also lived in the 19th century, during a time when the study of natural history was rapidly developing.
Voyage
Wallace undertook expeditions to the Amazon and Malay archipelago from 1848 to 1852 and 1854 to 1862, respectively.
Evidence
Wallace observed similar patterns of variation and adaptation in different regions, leading him to independently propose the theory of natural selection
ANDREW BERRY: The notion was that species changed one into another through time.
Contributions to the theory of Natural Selection
Both Darwin and Wallace observed that species exhibit variation and adapt to their environments.
They proposed that individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring.
They argued that over time, this process of natural selection leads to the evolution of species and the diversity of life on Earth.
