<h2>Jean Baptiste Lamarck</h2>
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 <em>Philosophie zoologique </em>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.
