Answer: Lamarckism, an evolutionary theory based on the principle that physical changes in organisms could be transferred to their offspring over their lifetime — such as greater development of an organ or a component through increased use. … In contrast, Darwin believed in evolutionary theory through natural selection.
What was the difference between the theories of Lamarck and Darwin?
Lamarck believed that organisms could acquire characteristics during their lifetime that they could pass down to their offspring, but Darwin did not believe these traits could be passed down. … Scientists accept Darwin’s theory of evolution because there is ample evidence to support it.

The five theories were: (1) evolution as such, (2) common descent, (3) gradualism, (4) multiplication of species, and (5) natural selection. Someone might claim that indeed these five theories are a logically inseparable package and that Darwin was quite correct in treating them as such.
