At the beginning of the 19th century, French scholar Lamarck (1744-1829) believed that animals and plants were living objects, and proposed the scientific term "biology" for the first time. He believed that biology should not only collect various biological specimens for classification and naming, but more importantly, study the interconnections between organisms and the laws of the occurrence and development of life. It was only from Lamarck that people referred to botany and zoology as "biology".

In 1727 he entered Lund University to study medicine. As early as 1730, he began to outline the classification of plants in his systematic study of plants.
