Rock-Paper-Scissors in Nature

The video explores the concept of rock-paper-scissors in nature, focusing on lizard behavior. It describes how different lizard types exhibit cyclic dominance similar to the game. The dynamics of these interactions are modeled mathematically, showing how population shifts occur. The video concludes with a brief human interaction about playing rock-paper-scissors.

What is surprising about the literature on rock-paper-scissors?

• It is only about human games.

• It is surprisingly extensive.

• It is very limited.

• It is mostly fictional.

Which type of lizard is known as 'ultra dominant'?

• Green lizards

• Orange lizards

• Yellow lizards

• Blue lizards

How do yellow lizards interact with other lizard territories?

• They form alliances with blue lizards.

• They disguise as females to infiltrate.

• They guard their own territory.

• They avoid all other lizards.

What is the relationship between orange and blue lizards?

• They have no interaction.

• Orange lizards can steal from blue lizards.

• Blue lizards dominate orange lizards.

• Orange lizards lose to blue lizards.

What is the cyclic dominance pattern among the lizards?

• Orange beats blue, blue beats yellow, yellow beats orange.

• Yellow beats orange, orange beats blue, blue beats yellow.

• Blue beats orange, orange beats yellow, yellow beats blue.

• Orange beats yellow, yellow beats blue, blue beats orange.

What happens when the population of blue lizards is high?

• It benefits the green lizards.

• It benefits the orange lizards.

• It benefits the red lizards.

• It benefits the yellow lizards.

How is the lizard population dynamics represented mathematically?

• As a circular chart.

• As a linear graph.

• As a square diagram.

• As a triangle diagram.

What can happen to the trajectories of lizard populations?

• They can spiral inwards or outwards.

• They always form closed loops.

• They remain static.

• They only spiral outwards.

What is the main similarity between lizard dynamics and the rock-paper-scissors game?

• Both are unpredictable.

• Both are based on chance.

• Both have a cyclic dominance pattern.

• Both involve human psychology.

When was the last time the speaker played rock-paper-scissors?

• When they were 5 years old.

• When they were 10 years old.

• When they were 15 years old.

• When they were 20 years old.
