Tiny toad offers big potential for research on plasticity

The video explores the fascinating world of spade foot toads, focusing on their unique ability to adapt through plasticity. Researchers David and Corinne Fennig study these toads to understand how plasticity influences evolution. The video highlights the different morphs of tadpoles and their dietary habits, as well as the behavioral plasticity in mate selection. The research underscores the importance of genetic and environmental factors in evolutionary processes.

What unique ability do spade foot toads possess that allows them to adapt to their environment?

• They can change their color.

• They can live without water.

• They can alter their forms and behaviors.

• They can fly short distances.

What are the two morphs that spade foot tadpoles can develop into?

• Carnivores and insectivores

• Insectivores and herbivores

• Omnivores and carnivores

• Herbivores and carnivores

What is the main focus of David and his group's research on spade foot toads?

• The toads' ability to fly

• The toads' migration patterns

• The toads' diet preferences

• The genetic basis of plasticity in tadpoles

How do female spade foot toads decide on their mates when their pond is drying up?

• They choose the largest male.

• They mate with males of their own species.

• They do not mate at all.

• They hybridize with males from another species.

What is a potential cost of hybridization for female spade foot toads?

• All male offspring will be sterile.

• All offspring will be sterile.

• All female offspring will be sterile.

• No offspring will survive.
