THE ISLAND RULE

The video covers highlights from NSF Science 360, including the island rule's effect on rodents, a discovery of magnetic fields in a nearby spiral galaxy, and the brain size differences between solitary and social wasps. It concludes with a prompt to explore more science news online.

What does the island rule suggest about animal sizes on islands?

• Larger animals become smaller, and smaller animals become larger.

• Larger animals become larger, and smaller animals become smaller.

• All animals become smaller.

• All animals become larger.

What recent discovery was made about rodents on islands?

• They do not follow the island rule.

• They are 17 times more likely to evolve to larger sizes.

• They become smaller than their mainland counterparts.

• They are less likely to evolve.

What was discovered in a nearby spiral galaxy that may explain the formation of spiral arms?

• A black hole

• A new planet

• A magnetic field coiled around the main arm

• A new star cluster

How do the brain sizes of solitary wasps compare to their social counterparts?

• Solitary wasps have smaller brains.

• Both have the same brain size.

• Social wasps have larger brains.

• Solitary wasps have larger brains.

What is a key difference between insect societies and vertebrate species regarding brain size?

• Insect societies have smaller brains despite social cooperation.

• Vertebrate species have smaller brains due to more social interaction.

• Vertebrate species have smaller brains due to less social interaction.

• Insect societies have larger brains due to social interaction.
