The modern synthesis [a] was the early 20th-century synthesis of Charles Darwin 's theory of evolution and Gregor Mendel 's ideas on heredity into a joint mathematical framework.

Neo-Darwinism is currently the most accepted theory of evolution. The biggest criticisers of Lamark’s theory were Mendel and August Weismann.Jan 11, 2020 · fluidquesty. Explanation: Darwin concluded that organisms become different over time and that all organisms have common ancestors. He also stated that the evolution of a population occurs slowly over an extended period of time and that natural selection is the process that drives evolution. This remarkable discovery was first noted by Darwin on September 1, 1833, and must have been made at some point during his second phase of collecting at Punta Alta, Argentina, the previous week ...Darwin's theory consisted of two main points; 1) diverse groups of animals evolve from one or a few common ancestors; 2) the mechanism by which this evolution takes place is natural selection.

The theory of evolution is one of the most widely accepted ways to explain all life on earth. At its center is how biology directs the evolution of species to create diversity and change in the natural world.

According to Darwin’s Theory of Evolution, the two causes of evolution are branching descent and natural selection. Climate, temperature, resource availability, and other environmental conditions all had a significant influence on the evolutionary process.

In evolutionary biology, punctuated equilibrium (also called punctuated equilibria) is a theory that proposes that once a species appears in the fossil record, the population will become stable, showing little evolutionary change for most of its geological history.
