Morphological adaptation refers to the evolutionary changes in the structure and form of organisms that enhance their ability to survive and reproduce in specific environments. These adaptations can include variations in body shape, size, or the development of specific physical traits like coloration, camouflage, or the ability to cope with environmental stresses. An example is the thick fur of polar bears, which aids in insulation against cold temperatures. Understanding morphological adaptations provides insights into the evolutionary processes and mechanisms of natural selection, highlighting how organisms adapt to their habitats over time.
