Can Math Explain How Animals Get Their Patterns?

The video explores how Alan Turing's mathematical rules can explain natural patterns like spots and stripes. Turing proposed a model involving activator and inhibitor substances, similar to predator-prey dynamics, to generate various patterns. By adjusting variables, different patterns such as spots, stripes, and labyrinths can form. While Turing's theory works on paper, scientists are still investigating its real-world applicability. Some biological systems, like those in mice, show Turing-like behavior, inspiring further research into natural pattern formation.

What did Alan Turing propose about the patterns found in nature?

• They are influenced by environmental factors.

• They are completely random.

• They are generated by a simple set of mathematical rules.

• They are solely determined by genetic blueprints.

In Turing's theory, what role does the activator play?

• It slows down the production of substances.

• It has no effect on the production of substances.

• It only affects the production of the inhibitor.

• It stimulates the production of both activator and inhibitor.

How can different patterns like spots and stripes be formed according to Turing's theory?

• By altering the genetic code of the organism.

• By changing the color of the activator.

• By increasing the temperature of the environment.

• By adjusting the spreading rate of the activator and inhibitor.

What is an example of a Turing-like system found in nature?

• The genetic blueprint of a fruit fly.

• The stripy ridges on the roof of a mouse embryo's mouth.

• The wings of a butterfly.

• The scales of a snake.

What is the significance of Turing's theory in modern biology?

• It has been completely disproven.

• It inspired biologists to explore patterns in living creatures.

• It is used to predict weather patterns.

• It is only applicable to computer science.
