Jean lamark is born
He was born in France on this day and started a new era of his own in science. In the town of Bazentine, Picardie. -
Begginning studies of his life
He was interested in botany, especially after his visits to the Jardin du Roi, and he became a student under Bernard de Jussieu, a notable French naturalist. Under Jussieu, Lamarck spent ten years studying French flora. -

Beggining of evolution thinking
On the influence of the moon on the Earth's atmosphere. Lamarck believed species were unchanging, however, after working on the molluscs of the Paris Basin, he was convinced that change in the nature of a species occurred over time. -

Hydrogeologie
In 1802 Lamarck published Hydrogéologie, and became one of the first to use the term biology in its modern sense.

Thus, the Earth's continents marched steadily westward around the globe. -
Recherches sur l'Organisation des Corps Vivants
That year, he also published Recherches sur l'Organisation des Corps Vivants, in which he drew out his theory on evolution. He believed that all life was organized in a vertical chain, with gradation between the lowest forms and the highest forms of life, thus demonstrating a path to progressive developments in nature. -
Jean Lamarck dies
On this day he dies though making many contributions to science and after 5 years someone steals body and no one know where it is.
