Natural Selection: the process in which organisms with certain characteristics that are better suited to their environment produce more offspring, leading to the prevalence of those characteristics in the population over time. Artificial Selection: the process in which humans deliberately select traits in organisms for breeding, producing a desired outcome. Adaptation: the process in which an organism’s traits become more suited to its environment, allowing it to survive and reproduce more effectively.

Charles Darwin is known as the father of evolution, this is because he made several discoveries that led to the theory of evolution A variation is any difference between individuals of the same species Some scientists asked how life on Earth got started and how it has changed over time throughout the planets history Charles Darwin and other scientists worked to develop a theory of evolution Theory of Evolution: the idea that species change over time, give rise to new species, and share a common ancestor

In 1831, Charles Darwin, 22, set aboard a British ship, the HMS Beagle, for a five year trip around the world Darwin was a naturalist, a person who observes and studies the natural world The captain wanted someone aboard the ship who could make and record observations as the crew explored South America

Darwin was surprised to see the diversity of living things he encountered during the voyage Today, scientists know organisms are even more diverse than Darwin had thought Scientists have calculated that there are millions of species on Earth, and new ones are being identified all the time Scientists have no way to estimate how many undiscovered species exist, but the numbers are believed to be very high

On his journey aboard the Beagle, Darwin also saw fossils of animals that had died long ago These fossils confused him, because though they looked like the living organisms they were also very different Darwin what happened to the organisms of long ago to cause a change in structure

Darwin collected birds from several of the Galapagos Islands From one island to the nest he noticed they were each a different type of finch He concluded that each finch species were each related to a single common ancestor species that came from the mainland Over time, different finches developed different beak shapes and sizes that was suited to the food they had to eat Beak shape is an example of an adaptation An adaptation is an inherited behavior or physical characteristic that helps an organism survive and reproduce in their environment

Based on his observations, Darwin reasoned that plants or animals that arrived on the Galapagos Islands faced conditions different than those on the nearby mainland Darwin hypothesized that species change over many generations and become better adapted to new conditions
Darwin's Hypothesis

A theory explains why and how things happen in nature A scientific theory is a well tested explanation for a wide range of observations and experimental results Darwin's theory concluded that organisms in the Galapagos had changed over time or evolved
Developing a Theory

Charles Darwin's book On the Origin of Species was once considered so controversial, it was banned from the Vatican Library. The first scientist to propose a theory of evolution was Jean-Baptiste Lamarck in 1809. The coelacanth, a large, lobe-finned fish long believed to be extinct, was discovered alive in 1938 off the coast of South Africa.
