Question

Humans begin their existence as a single undifferentiated cell and proceed to become a highly complex and organized system consisting of specialized cells (liver, skin, brain, blood, etc.). This change BEST exemplifies the ____ principle.

Answer 1

Answer:

Orthogenetic

Explanation:

• The Orthogenetic principle of development was put forward by Heinz Werner, in the year 1975.
• It is a biological principle of development.
• This principle of development states that all the aspects of the functioning of a living organism develop progressively from a less differentiated state to a more differentiated state.
• Besides differentiation, there is also hierarchic integration and articulation of functioning such as perception, cognition, etc.
• This leads to the development of more complex forms from a simple form.
• Therefore, a single undifferentiated cell giving rise to the complex organized system is an example of the orthogenetic principle.
