He was an american botanist, ecological pioneer and conservationist, who influenced the early study of plant communities, particularly the process of plant succession, which later became a fundamental tenet of modern ecology. His studies of plant life in the Indiana Dunes made him one of America's most notable early ecologists.

French mathematician, scientist, and philosopher. He was one of the first to abandon scholastic Aristotelianism, because he formulated the first modern version of mind-body dualism, he promoted the development of a new science grounded in observation and experiment, he has been called the father of modern philosophy. Applying an original system of methodical doubt, he dismissed apparent knowledge derived from authority, the senses, and reason and erected new epistemic foundations on the basis of the intuition that, when he is thinking, he exists.

Jean Baptiste Lamarck (1744-1829)

The first was that the environment gives rise to changes in animals. He cited examples of blindness in moles, the presence of teeth in mammals and the absence of teeth in birds as evidence of this principle. The second principle was that life was structured in an orderly manner and that many different parts of all bodies make it possible for the organic movements of animals.

Although he was not the first thinker to advocate organic evolution, he was the first to develop a truly coherent evolutionary theory. He outlined his theories regarding evolution first in his Floreallecture of 1800, and then in three later published works:

• Recherches sur l'organisation des corps vivants, 1802.
• Philosophie Zoologique, 1809.
• Histoire naturelle des animaux sans vertèbres, (in seven volumes, 1815–1822).

Aristotle (383 A.C- 322 A.C)

He was the first person to give a definition for nature:  is an inner principle of change and being at rest. This means that when an entity moves or is at rest according to its nature reference to its nature may serve as an explanation of the event. The nature of the entity is in and of itself sufficient to induce and to explain the process once the relevant circumstances do not preempt it.
