PHYLOGENESIS
INVESTIGATIONS OF RUSSIAN
SCIENTIST A.N. SEVERTSOV
WAS OPENED CONNECTION
BETWEEN ONTOGENESIS AND
PHYLOGENESIS . ACCORDING
TO HIS THEORY THE SOURCE
OF PHYLOGENETIC
TRANSFORMATIONS IN
CHANGES ARISING ON EARLY
STAGES OF ONTOGENESIS
,NOT IN ADULT FORMS
.EMBROYONIC CHANGES
REFLECTED ON THE STRUCTURE
OF ADULT FORMS AND HAVING
EVOLUTIONAL IMPORTANCE
ARE CALLED AS
PHYLOEMBROYOGENESIS.
