Question

What is environmental constraint in Darwinian's view?

a) An organism's ability to adapt to any environment.
b) The limitation imposed by the external environment on the survival and reproduction of organisms.
c) The absence of environmental factors affecting adaptation.
d) The unrestricted variability of the environment.

Answer 1

In Darwin's view, environmental constraint is the limitation imposed by the environment on organism survival and reproduction, crucial to natural selection.

Step-by-step explanation:

In Darwinian view, an environmental constraint refers to b) The limitation imposed by the external environment on the survival and reproduction of organisms. This concept is central to the theory of natural selection, where the environment plays a critical role in determining which organisms with certain heritable traits are more likely to survive and reproduce. For example, the beak size of Darwin's finches changing due to the availability of different-sized seeds is a classic example of an adaptation to environmental constraints, where only the birds with beaks suited to the available seed types were able to eat effectively and survive to reproduce.
