Understanding Natural Selection

What is a key characteristic of Lithipodius nulla's offspring?

• Offspring do not inherit traits from parents.

• Offspring cannot survive in different environments.

• All offspring are identical.

• Each offspring is unique, with variations.

Why is variation important for the survival of a species?

• Variation does not affect survival.

• It ensures all individuals are the same.

• It prevents offspring from inheriting traits.

• It allows for adaptation to changing environments.

What does natural selection favor?

• Traits that hinder survival

• Characteristics that are less suited for survival

• The ability to reproduce without variation

• Traits best suited for the environment

How does natural selection affect a population over time?

• It leads to the accumulation of favorable traits.

• It increases the population size.

• It ensures all individuals are identical.

• It decreases genetic diversity.

What is adaptation?

• A decrease in population size

• A transformation to suit the environment

• The process of individuals becoming identical

• A reduction in genetic variation

How do environmental pressures influence a species?

• They ensure all individuals are the same.

• They have no impact on species.

• They reduce the need for variation.

• They lead to new adaptations if variation exists.
