Answer
An evolutionary constraint is a limitation or restriction on the course of evolutionary change.
Solution
a
Genetic constraints: These are limitations due to the genetic makeup of an organism. For example, certain traits may not evolve because the necessary genetic variation is not present in the population
b
Developmental constraints: These occur when certain developmental pathways limit the range of possible phenotypes. For instance, the way an organism develops from an embryo can restrict the types of changes that can occur
c
Functional constraints: These are limitations due to the functional requirements of an organism. For example, certain structures may not evolve because they would interfere with essential functions like breathing or reproduction
Key Concept
Evolutionary constraint
Explanation
Evolutionary constraints are factors that limit the ability of a population to adapt to changing environments. These constraints can be genetic, developmental, or functional, and they play a crucial role in shaping the evolutionary pathways available to organisms.
