Skin Pattern
* Select the correct answer into all dropdown fields. You need to answer all questions before clicking verify button.
Animals have different skin patterns, such as spots, stripes, and hexagons. Scientists can explain how these patterns help animals adapt to their environment, but they don't know how they are formed in the first . Turing was a scientist who suggested that two chemicals in the skin can interact to form patterns by balancing each other out. But his theory could not explain why some animals have clear lines between different colors, like zebras and boxfish. Alessio and Gupta are two scientists who improved Turing's theory a new factor. They said that larger things in the skin, like color cells, can move because of smaller things, like soap molecules. They showed that this can make more defined patterns by color cells into different areas. They also showed that their theory can create the same hexagon pattern as the boxfish, which Turing's theory could not do. Their work indicates that this new factor may be for creating animal skin patterns and other natural patterns.
