Lamarck's theory posits changes are introduced to theÊ species and passed down through the generations. Second, constant use causes a trait to manifest, disuse causes it to disappear. Third, traits changed or acquired during a subject's lifetime are passed down to its offspring. Fourth, evolution takes place gradually.
Evolution Theory, Force Theory, Divine Right Theory, Social Contract Theory
The four sources of supporting evidence for the theory of evolution are fossils, the development of life forms, changes over life forms over the years and the way in which related species are distributed across the world.
Overproduction, variation, selection, and adaptation
1. the animals are stupid duhhlol
God loves u have an amazing day!
You can find evolution stones is various places. If you have beaten the Elite Four, go to the Pokeathlon Dome. In the prizes section, there will be evolution stones. Compete in competitions to earn enough points for the one you want.
There are no stages to evolution. It is a continuous process of adaptation and divergence.
Abiogenesis, or more commonly known as the origin of life itself, is not part of Darwin's theory of evolution.
There are four main tenets of Darwin's theory of evolution by natural selection. They are the idea that with each generation individuals are produced that can survive, the concept that phenotypic variation exists, those with heritable traits for a specific environment have the ability to survive in that environment, and the idea that new species form during reproductive isolation.
These four factors can effect ways evolution occur: 1.) Mutation 2.) Selection3.) Gene Flow4.) Genetic Drift
The shortest distance between four points is a straight line to and from each individual point. If all four points are aligned, the result will be a single straight line through all four points.
Aristotle came up with the theory of the four elements in the world needing to be in balance. Hippocrates based his theory of Four humours in a sinilar vein, linking illness to the four seasons.
