Natural and Sexual Selection in Evolution

What does sexual selection primarily focus on?

• Avoiding diseases

• Competing for mates

• Finding food

• Surviving predators

Which trait was considered not beneficial for the hypothetical bird?

• Long-bill

• Awkward

• Burly

• Armored Shield

What advantage did the Long-bill trait provide?

• Stronger defense against predators

• Faster flight

• Access to new food sources

• Better camouflage

What is the primary goal of sexual selection?

• To enhance foraging efficiency

• To increase mating opportunities

• To improve survival rates

• To strengthen defense mechanisms

How does the distribution of food resources affect sexual selection?

• It influences the development of traits for food gathering

• It has no effect

• It decreases the importance of sexual selection

• It determines the type of competition or choice in mating

How does male-male competition influence trait development?

• Males develop traits for faster flight

• Males become larger or stronger

• Males develop traits for better camouflage

• Males become smaller

Why do females not develop the same traits as males in sexual selection?

• All of the above

• Females do not compete for mates

• Natural selection favors different traits in females

• Females are not affected by sexual selection

What triggers female choice in mate selection?

• The ability of males to avoid predators

• Ornaments or traits that males display

• The physical strength of males

• The ability of males to gather food

Why might a trait that decreases survival still become widespread?

• It offers better camouflage

• It aids in finding food

• It attracts more mates

• It helps in avoiding predators

What is the ultimate result of both natural and sexual selection?

• Creating a uniform population

• Increased food resources

• Elimination of predators

• Passing on genes to the next generation
