Why are advantageous traits more likely to be passed on to the offspring?

Which of the following would be considered a physiological adaptation?

• Human ability to sweat for evaporative cooling
• Hollow bones in birds allowing for flight
• The blubber in bears allowing them to hibernate.
• Webbed toes in frogs allowing for efficient water movement.

In the Pom Poms and Predator Tools lab, what seemed to determine which adaptations were successful? 

• It was random. Nothing was more successful. 
• The individuals that best fit in with their environment were more successful 
• The pom poms that showed up more against their environment survived
• The tool that was hardest to use captured the most pom moms
