Evolutionary Adaptations

Click on the flashcard to see the answer



What is an evolutionary adaptation?

An evolutionary adaptation is a heritable characteristic that enhances an organism's ability to survive and reproduce in its environment.

How does natural selection lead to adaptation?

Natural selection favors traits that improve survival and reproductive success, resulting in evolutionary adaptations.

What is an example of a behavioral adaptation?

Migration in birds is an example of a behavioral adaptation to seasonal changes.

What is the significance of camouflage as an adaptation?

Camouflage allows organisms to blend with their surroundings, enhancing their chances of avoiding predators.

Why are arctic foxes' white fur an example of physical adaptation?

Their white fur provides camouflage in snowy environments to avoid predators and hunt effectively.

How do desert plants exhibit physiological adaptations?

Desert plants, such as cacti, show physiological adaptations through efficient water storage and reduced evaporation.

What role does genetic variation play in evolutionary adaptations?

Genetic variation provides the raw material for natural selection to act upon, leading to adaptation.

How do bacteria develop antibiotic resistance as an adaptation?

Bacteria can acquire mutations or gene exchanges that confer resistance to antibiotics, aiding their survival.

What is an example of co-evolution?

Co-evolution is seen in flowering plants and their pollinators, where both evolve traits benefiting each other.

How is mimicry a form of adaptation?

Mimicry is when one species evolves to resemble another, often for protection or predation.

What are vestigial structures, and how do they relate to adaptation?

Vestigial structures are remnants of features that were functional in an ancestral species, hinting at evolutionary change.

What is convergent evolution?

Convergent evolution occurs when unrelated species evolve similar traits due to similar environmental pressures.

Can evolutionary adaptations occur rapidly? Provide an example.

Yes, evolutionary adaptations can occur rapidly, such as the development of pesticide resistance in insects.

How do structural adaptations differ from behavioral adaptations?

Structural adaptations are physical features, while behavioral adaptations involve actions for survival.

What are some examples of adaptation in mammals that live in aquatic environments?

Examples include streamlined bodies, webbed feet, and blubber for insulation.
