To explain: The difference in the usefulness of adaptive and non-adaptive variations for phylogenetic inference.
Introduction: The process of modification by an organism to increase its survival better in a changed environment is termed as adaptation. Adaptation plays a crucial role in the evolution of an organism. The traits inherited by an organism from their primitive ancestor are called primitive ancestors traits, while the characteristics developed due to adaptation are adaptive traits.
To explain: The ways in which knowledge of a character’s adaptive function influences the judgment of whether or not the character provides evidence for real relationships among taxa.
Introduction: The process of modification by an organism to thrive better in a changed environment is termed as adaptation. Adaptation plays a crucial role in the evolution of an organism. The traits inherited by an organism from their primitive ancestor are called primitive ancestor traits, while the characteristics developed due to adaptation are adaptive traits.

She recently returned from a trip to sub-Saharan Africa, where she did not take malaria prophylaxis. On examination, she is febrile (39.8°C/103.6°F) and hypotensive. Laboratory studies reveal hemoglobin of 8.0 g/dL, platelet count of 50,000/μL, and evidence of hemoglobinuria. A peripheral blood smear shows ring forms and banana-shaped gametocytes.
