PCB 3063: Exam 1
Variation is a characteristic that can be inherited. Every organism group overproduces
offspring leading to a struggle for survival. Individuals with favorable characteristics are
more likely to survive, passing their genes leads to evolution. - ✔️✔️Theory of organic
evolution by natural selection
The male semen was only formed from the blood ~ provides "form"
The female menstrual blood contains the "matter"
The "form" controls and shapes the "matter" into mature offspring -
✔️✔️Comprehensive theory of inheritance
All parts of the embryo are present potentially in the egg.
The organism evolves by gradual building up and aggregation of these parts
De novo - ✔️✔️Epigenesis
Genetics is the study of _________ in all its manifestations - ✔️✔️Heredity
The main subject genetics revolves around - ✔️✔️Genes
"Of the semen, I assert that it is secreted by the whole body, healthy by healthy parts,
sick by sick parts" - ✔️✔️Hippocrates
"More people become able by exercise than by their natural predisposition" -
✔️✔️Democritus
Advocated for the selection of spouses to produce children who will develop into bodily
and ethically eminent personalities - ✔️✔️Plato
Who developed the comprehensive theory of inheritance? - ✔️✔️Aristotle
Who proposed that all living things originate from an egg? - ✔️✔️Harvey
Who founded epigenesis? - ✔️✔️Aristotle
Who discovered spermatozoa? - ✔️✔️Leeuwenhoek
Speculated that sperm provide the essential life giving properties and the egg furnishes
the proper environment for the embryo's nutrition and development -
✔️✔️Leeuwenhoek
, The organism is contained in one of the sex cells as a fully developed
______________. - ✔️✔️Homunculus
Theory of: Homunculus ---> Adult - ✔️✔️Preformationism
Who believed that the homunculus was found in the sperm? - ✔️✔️Spermist
Who believed that the homunculus was found in the egg? - ✔️✔️Ovists
Who discredited the theory of preformationism? - ✔️✔️Wolff
Who proposed the FIRST theory of evolution? - ✔️✔️Jean Baptiste de Lamarck
Change in environment --> change in organ structure/size, change in needs
All changes are inherited - ✔️✔️Theory of the inheritance of acquired characteristics
Who proposed the theory of organic evolution by natural selection? - ✔️✔️Charles
Darwin
Darwin's theory demolished Linnaean concept of: - ✔️✔️Fixity of species
Darwin proposed the: - ✔️✔️Provisional hypothesis of pangenesis
Cells of developing organisms are capable of producing ________, which are exact but
minute copies of each body part. - ✔️✔️Gemmules
Gemmules are carried by the blood to the ______ where they: - ✔️✔️Reproductive
organs; assembled into gametes
With fertilization the combined gemmules then: - ✔️✔️separate out to different parts of
the body during fertilization
Who disproved of Pangenesis? - ✔️✔️August Weismann
Who proposed the germplasm theory of heredity? - ✔️✔️Weismann
Germplasm theory: multicellular oraganisms are made of ____ types of tissue. -
✔️✔️Two
Body tissues= - ✔️✔️Somatoplasm
Hereditary material= - ✔️✔️Germplasm
