Evolution is the theory that all the kinds of living things that exist today developed from earlier types. The differences between them resulted from changes that happened over many years. The simplest forms of life arose at least 3.5 billion years ago. Over time they evolved into the millions of species, or types, of living things alive today.

Although there were a number of natural historians in the 18th century who had some idea of evolution, the first well-formed ideas came in the 19th century. Three biologists are most important.
Darwin's On the Origin of Specieshas two themes: the evidence for evolution, and his ideas on how evolution took place. This section deals with the second issue.
This was an important movement in evolutionary biology, which started in the 1930s and finished in the 1950s. It has been updated regularly ever since. The synthesis explains how the ideas of Charles Darwin fit with the discoveries of Gregor Mendel, who found out how we inherit our genes. The modern synthesis brought Darwin's idea up to date. It br...
Co-evolution
Co-evolution is where the existence of one species is tightly bound up with the life of one or more other species. New or 'improved' adaptations which occur in one species are often followed by the appearance and spread of related features in the other species. The life and death of living things is intimately connected, not just with the physical environment, but with the life of other species. These relationships may continue for millions of years, as it has in the pollination of flowering...
Tree of life
Charles Darwin was the first to use this metaphor in biology. The evolutionary tree shows the relationships among various biological groups. It includes data from DNA, RNA and protein analysis. Tree of life work is a product of traditional comparative anatomy, and modern molecular evolution and molecular clockresearch. The major figure in this work is Carl Woese, who defined the Archaea, the third domain (or kingdom) of life. Below is a simplified version of present-day understanding.
Macroevolution
Macroevolution: the study of changes above the species level, and how they take place. The basic data for such a study are fossils (palaeontology) and the reconstruction of ancient environments. Some subjects whose study falls within the realm of macroevolution: 1. Adaptive radiation, such as the CambrianExplosion. 2. Changes in biodiversitythrough time. 3. Mass extinctions. 4. Speciationand extinction rates. 5. The debate between punctuated equilibrium and gradualism. 6. The role of developm...

Feb 23, 2023 · Kids are really good thinkers if you give them a chance. We talk about creationist theory and, let’s face it, there’s a chance that it’s true. If God created all the animals and plants and set them up with DNA, put them all on the planet, and put the fossils down as well, that works as a theory.”. “What I say to my kids is, ‘Try to ...
