CHAPTER, XV Iti 
LAMARCK S THEORY AS TO“THE’ EVOLUTION ‘OF 
MAN 
LAMARCK’S views on the origin of man are con- 
tained in his Recherches sur l Organisation des Corps 
vivans (1802) and his Phzlosophte soologique, pub- 
lished in 1809. We give the following literal trans- 
lation in full of the views he presented in 1802, and 
which were probably first advanced in lectures to his 
classes. 
‘“ As to man, his origin, his peculiar nature, I have 
already stated in this book that I have not kept 
these subjects in view in making these observations. 
His extreme superiority over the other living crea- 
tures indicates that he is a privileged being who has 
in common with the animals only that which con- 
cerns animal life. 
‘“TIn truth, we observe a sort of gradation in the 
intelligence of animals, like what exists in the grad- 
ual improvement of their organization, and we re- 
mark that they have ideas, memory; that they think, 
choose, love, hate, that they are susceptible of jeal- 
ousy, and that by different inflexions of their voice 
and by signs they communicate with and understand 
each other. It is not less evident that man alone is 
endowed with reason, and that on this account he is 
clearly distinguished from all the other productions 
of nature.
