<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.

Maksim231197 [3]

The hormone to be given is oxytocin. Oxytocin is a hormone produced by the paraventricular nuclei of the hypothalamus then stored in the posterior pituitary gland (along with antidiuretic hormone or vasopressin) that is responsible mainly for uterine contraction and milk ejection or letdown. Oxytocin induces contraction of the myoepithelial cells in the breast for milk letdown. On the other hand, there is upregulation of oxytocin receptors during parturition which makes the uterus more sensitive to oxytocin. Oxytocin is also known to induce labor and reduce post-partum bleeding.
