Condensation of some of the phylogenetic events and elimination of others in the embryonic development is referred to as
Open in App
Solution
The correct option is C Tachygenesis
In biology, the inheritance of a characteristic at an earlier stage of individual development than that at which it first appeared acceleration of development. According to the theory of tachygenesis, new characteristics are first acquired by adult organisms are inherited at earlier and earlier periods in the lives of their descendants and finally the older characteristics are crowded out and dropped from the beginning of the embryonic history, thus making room for the new characteristics, which are continually being added on to the organism during its adult life. Thus, option C is correct.
Ontogeny (also ontogenesis or morphogenesis) is the origination and development of an organism, usually from the time of fertilization of the egg to the organism's mature form. Yet, the term can be used to refer to the study of the entirety of an organism's lifespan. Thus, option D is wrong.
The introduction during embryonic development of characters or structure not present in the earlier evolutionary history of the strain or species, as opposed to palingenesis is called as coenogenesis. Thus, option B is wrong.
The apparent repetition, during the development of a single embryo, of changes that occurred previously in the evolution of its species is called palaeogenesis. Thus, option A is wrong.
