jean baptiste lamark?

Question

Jean Baptiste Lamark is commonly remembered for his discredited theory of inheritance of acquried traits. However many biologists including Darwin have respected him as a zoologist and evolutionary biologist. How did Lamark contribute to cell theory before the work of Shleiden and Schwann

Answer 1

The website listed below tells many scientists' contribution to cell theory. The section about Lamarck says:

JEAN-BAPTISTE DE LAMARCK
The majority of this Frenchman's work (1744 - 1829) dealt with animal classification and evolution. He is credited with taking steps towards the creation of the cell theory with this saying:


"Every step which Nature takes when making her direct creations consists in organizing into cellular tissue the minute masses of viscous or mucous substances that she finds at her disposal under favorable circumstances."

Answer 2

Lamarck published a series of books on invertebrate zoology and paleontology. Of these, Philosophie Zoologique, published in 1809, most clearly states Lamarck's theories of evolution. The first volume of Histoire naturelle des Animaux sans vertèbres was published in 1815, the second in 1822. Aside from Lamarck's contributions to evolutionary theory, his works on invertebrates represent a great advance over existing classifications; he was the first to separate the Crustacea, Arachnida, and Annelida from the "Insecta." His classification of the mollusks was far in advance of anything proposed previously; Lamarck broke with tradition in removing the tunicates and the barnacles from the Mollusca. He also anticipated the work of Schleiden & Schwann in cell theory in stating that:
". . . no body can have life if its constituent parts are not cellular tissue or are not formed by cellular tissue."

Answer 3

i do no longer hate Charles Darwin, i individually particularly like him. I even have great comprehend for what he did. He knew the end results of his learn and struggled with whether or to no longer launch his findings, particularly pondering the certainty that his spouse replaced right into a non secular Christian. He replaced into merely affirming what he mentioned and his theories as to what might clarify it. He additionally gave numerous situations that could prepare or disprove his theories could they be met or no longer. it form of sounds like he replaced into an clever, considerate, humble guy. i individually have self assurance that for the time of reality someplace between evolution and BAM God zapped each and everything into being. additionally, you're superb, i've got by no potential heard of Watt or Lamark. yet neither of them should be hated via all people.
