How is variation different from adaptation? * Variations are physical or behavioral traits that make an organism better suited to its environment while adaptation comes from random mutations. no answer Variation is a difference within an individual organism from the rest of the population. An adaptation is a feature that helps an organism survive in its environment. Adaptation is a difference within an individual organism from the rest of the population. A variation is a feature that helps an organism survive in its environment. Variation is always caused by mutation while adaptation is a heritable trait. Which of the following BEST explains Darwin's observation on populations of various species that seemed well-suited to their environment? * Species had been introduced to particular areas by humans on purpose. no answer Species might be able to adapt to their surroundings over time. The species Darwin saw were all related to each other. Some environments rarely ever change.

Ecological adaptations

An ecological adaptation is any morphological, physiological, or behavioral trait of an organism that allows it to survive and reproduce in a habitat or ecosystem. Adaptation is a biological mechanism by which an organism gradually gets more acclimated to its surroundings.
