HISTORY of Developmental Biology Flashcards
Who discovered the INCUBATION?
EGYPTIANS 1400 BC
What is the contribution of HIPPOCRATES (460-370 BC)
Embryo Development
Founder of Embryology
Aristotle
He studied embryos of different organisms by opening
up bird eggs at different stages of development and
dissecting mammalian and cold-blooded embryos.
Aristotle
His main Contribution in Dev. Biology is the discovery SEMEN AND RECAPITULATION
ARISTOTLE
He is credited as being a vitalist (life arises
from or contains a nonmaterial vital
principle) and teleologist (all life and
actions are driven by an ultimate purpose)
whose main contribution to embryology
was his steadfast belief that the umbilical
cord was necessary for respiration

LEONARDO DA VINCI

WILLIAM HARVEY
1578-1657
He described embryo development as a
simple unfolding of an already miniature
adult organism.

PREFORMATION
THEORY OF HOMUNCULUS
MARCELLO MALPHIGI
1628-1694
He discovered the follicles of the mammalian ovary
in dogfish and demonstrated that the human female ovary was homologous to the ovaries in previously
studied oviparous animals.
