(1744-1829) was an important French naturalist. He was one of the first scientists to propose that species change over time. idea of the inheritance of acquired characteristics. Like him, Darwin assumed that species can change over time. The fossils he found helped convince him of that.
I. An organism recognizes the need for a change.
II. An organism will react to the recognition of the need for a change.
III. By use or disuse and organism modifies its structure to satisfy the recognition of need for a change.
IV. Characteristics acquired as a result are passed on

Explanation:

Jean Baptiste Lamarck (1744-1829) was an important French naturalist. He was one of the first scientists to propose that species change over time.

Jean Baptiste Lamarck published his theory of evolution in the book Philosophie zoologique called the theory of use and disuse or the inheritance of acquired characteristic. According to this theory, ecological conditions in which an organism lives cause it to have certain needs. These needs are met by modification of old organs or by production of new rudimentary organs.The continuous  use of the rudimentary structures allows them to increase in size and disuse causes that organ to degenerate. These changes become fix and become inheritable.

the core of the sun is so hot and there is so much pressure, nuclear fusion takes place, hydrogen is changed to helium. nuclear fusion creates heat and photons. when the heat reaches the earth it warms the molecules of the atmosphere, and they warm other molecules and so on.
