Jean Baptiste de Lamarck and Charles Darwin both had speculated about the evolution process through their theories. These two theories provide varying suggestions and obvious differences ranging from the mechanism of evolution to the vast diversity of life on earth. Read on to explore how these two theories were different from each other.

|
| Darwinism | Lamarckism |
| This theory discredits the Internal Vital Force theory | Lamarckism strongly builds on the notion of Internal Vital Force in organisms |
| Development or disappearance of an organ happens due to continuous variations | From an evolutionary perspective, organs develop if they are constantly used. If unused, it could disappear |
| Darwinism emphasises the struggle for existence | Lamarckism discredits the struggle for existence |
| Only useful variations are transferred to the succeeding generation | All acquired traits are transferred to the next generation |
| Darwinism was built on the principle of survival of the fittest | Lamarckism was not built on the notion of survival of the fittest |
