What is an evolutionary adaptation?
Click to flip
An evolutionary adaptation is a heritable characteristic that enhances an organism's ability to survive and reproduce in its environment.
Click to flip
How does natural selection lead to adaptation?
Click to flip
Natural selection favors traits that improve survival and reproductive success, resulting in evolutionary adaptations.
Click to flip
What is an example of a behavioral adaptation?
Click to flip
Migration in birds is an example of a behavioral adaptation to seasonal changes.
Click to flip
What is the significance of camouflage as an adaptation?
Click to flip
Camouflage allows organisms to blend with their surroundings, enhancing their chances of avoiding predators.
Click to flip
Why are arctic foxes' white fur an example of physical adaptation?
Click to flip
Their white fur provides camouflage in snowy environments to avoid predators and hunt effectively.
Click to flip
How do desert plants exhibit physiological adaptations?
Click to flip
Desert plants, such as cacti, show physiological adaptations through efficient water storage and reduced evaporation.
Click to flip
What role does genetic variation play in evolutionary adaptations?
Click to flip
Genetic variation provides the raw material for natural selection to act upon, leading to adaptation.
Click to flip
How do bacteria develop antibiotic resistance as an adaptation?
Click to flip
Bacteria can acquire mutations or gene exchanges that confer resistance to antibiotics, aiding their survival.
Click to flip
What is an example of co-evolution?
Click to flip
Co-evolution is seen in flowering plants and their pollinators, where both evolve traits benefiting each other.
Click to flip
How is mimicry a form of adaptation?
Click to flip
Mimicry is when one species evolves to resemble another, often for protection or predation.
Click to flip
What are vestigial structures, and how do they relate to adaptation?
Click to flip
Vestigial structures are remnants of features that were functional in an ancestral species, hinting at evolutionary change.
Click to flip
What is convergent evolution?
Click to flip
Convergent evolution occurs when unrelated species evolve similar traits due to similar environmental pressures.
Click to flip
Can evolutionary adaptations occur rapidly? Provide an example.
Click to flip
Yes, evolutionary adaptations can occur rapidly, such as the development of pesticide resistance in insects.
Click to flip
How do structural adaptations differ from behavioral adaptations?
Click to flip
Structural adaptations are physical features, while behavioral adaptations involve actions for survival.
Click to flip
What are some examples of adaptation in mammals that live in aquatic environments?
Click to flip
Examples include streamlined bodies, webbed feet, and blubber for insulation.
