Concept explainers

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.

How can embryos help scientists understand evolution? Embryos go through various stages that suggest the animal’s evolutionary process. Embryos are frequently fossilized and illustrate change over time. Embryos provide evidence for which life forms existed at the same time. Embryos contain the code for all life on Earth.
Use the vertebrate lineage to explain how the cutaneous system (the skin) changed and evolved to life on land. Include which classes contributed key features and advancements. Your focus is on terrestrial vertebrates, but explain the basics of aquatic skin to show where the story started. Include how each change benefited that lineage in terms of their evolution to land (what niches did each new feature allow). HINT: Sometimes it's helpful to think in terms of Pros and Cons of the evolution of a feature. If you know I am looking for a word - bold or underline it. If there is the material you need to draw to support your answer upload that in the second question.
