Lamarck’s Theory of Evolution, also known as Lamarckism, provides a historical context to the currently prevalent concept of genetic inheritance. Jean-Baptiste Lamarck was the first to postulate a coherent evolutionary theory about the drivers/ forces of evolution. Despite the theory being rejected, he is still regarded as a pioneer in the subject of evolutionary change.
According to Darwin’s evolutionary theory, natural selection is a matter of reproductive success. The “fittest” individuals are the ones who have the combination of traits that allow them to survive longer and produce more offspring. Those beneficial traits will be inherited by next generations.

Although the modern theory of biological evolution by natural selection is well accepted among professional biologists, there is still controversy about whether natural selection selects for fit genes or fit organisms or fit species. Evolution by natural selection is a theory about the process of change.
According to. In the history of human evolution, walking upright dates back at least 6m years to Sahelanthropus, an ancient species with both ape and human features discovered from fossil remains.
According to evolutionary theory, there is a specific reason that certain animals live in the regions that they do. Polar bears, for instance, are found only in the Arctic regions of the world. An evolutionary theorist would say that the polar bear was best adapted for this type of environment, unlike a grizzly bear, who would freeze to death.

If evolution proceeds as we should expect from modern theory, then this plethora and confusion of species concepts is easily explained — evolution is a gradual process at genetic and behavioral scales (but it can be abrupt at geological and ecological scales), and so we will see species in all kinds of stages of speciation, extinction.
