Natural Selection + Animal Adaptations

An inherited trait that helps those organisms that have it to survive

• niche
• structure
• characteristic
• adaptation

The ability to be unaffected by something usually harmful

• Resistance

• Mutation

• Natural Selection

• Adaptation

Process in which traits become more/less common due to some traits making it more likely for individuals to survive and reproduce

• Natural Selection

• Mutation

• Distribution

• Adaptation

A random and permanent change to a gene

• Protein

• Gene

• Natural Selection

• Mutation

Why/how do population change over time?

• The environment changes

• There is a heritable trait which doesn't help survival

• Natural selection causes a trait to become more common in the population

• The organism decides to have a mutation occur

Mutations are...

• beneficial when it helps survival and reproduction

• neutral when it doesn't help or hinder survival and reproduction

• harmful when it lowers the chance for survival and reproduction

Why is it beneficial for a species to have varying traits?

• They can't be seen by predators

• It is helpful in asexual reproduction

• If the environment changes, the population might be better able to adapt

• They don't recognize each other.

Traits become more common in a population when it increases the probability of

• survival

• mutations

• reproduction

• dying

Mutations are a change in what?

• DNA
• tRNA
• genotype
• phenotype

Which organisms are most likely to survive?

• the best adapted
• the fastest
• the strongest
• the most domesticated (tamed)
