Darwinian Theory

Charles Darwin's contributions to science include the theory of evolution, which posits that species change over time through natural selection. This theory is foundational in understanding biological diversity and is supported by various scientific methods and evidence, including the fossil record and genetic mutations.

Evolution is considered science because it is observable and testable

Genetic mutation

The Fossil record

Species

Speciation is the evolutionary process by which new biological species arise
a group of related organisms that share a distinctive form and are capable of interbreeding and producing an offspring that interbreeds

Natural Selection

Evolution shows us that species are not immutable but that they change over time through natural selection
the process by which new species were brought into existence.

Evolution according to Darwin was studied on four scales

Chemical
Biological
Geological
