Universal evolution is a theory of evolution formulated by Pierre Teilhard de Chardin and Julian Huxley that describes the gradual development of the Universe from subatomic particles to human society, considered by Teilhard as the last stage.
Universal Darwinism, also known as generalized Darwinism, universal selection theory, [1] or Darwinian metaphysics, [2] [3] [4] is a variety of approaches that extend the theory of Darwinism beyond its original domain of biological evolution on Earth. Universal Darwinism aims to formulate a generalized version of the mechanisms of variation ...
The tree of life or universal tree of life is a metaphor, conceptual model, and research tool used to explore the evolution of life and describe the relationships between organisms, both living and extinct, as described in a famous passage in Charles Darwin's On the Origin of Species (1859). [1]
Professor of biology Jerry Coyne sums up biological evolution succinctly: [3]. Life on Earth evolved gradually beginning with one primitive species – perhaps a self-replicating molecule – that lived more than 3.5 billion years ago; it then branched out over time, throwing off many new and diverse species; and the mechanism for most (but not all) of evolutionary change is natural selection.
Evolutionary logic is a theory of rationality where logical law emerges as an intrinsic aspect of evolutionary biology. William S. Cooper, in his 2001 book The Evolution of Reason: Logic as a Branch of Biology, illustrates how logical rules are derived directly from evolutionary principles. [14]
In the early 19th century prior to Darwinism, Jean-Baptiste Lamarck (1744–1829) proposed his theory of the transmutation of species, the first fully formed theory of evolution. In 1858 Charles Darwin and Alfred Russel Wallace published a new evolutionary theory, explained in detail in Darwin's On the Origin of Species (1859). Darwin's theory ...

Evolutionary theory predicted that since amphibians evolved from fish, an intermediate form should be found in rock dated between 365 and 385 million years ago. Such an intermediate form should have many fish-like characteristics, conserved from 385 million years ago or more, but also have many amphibian characteristics as well.
