• Darío

• Delfino

Choose the three evolution mechanisms

• Natural selection

• Mutation

• Time

• Variation

Mutation and recombination produce genetic...

• Time

• Variation

• Selection

It occurs by chance

• Mutation

• Recombination

• Variation

• Time

Allows the better -adapted organism to survive while others are eliminated

• Natural selection

• Time

• Variation

Variation, natural selection and time

• Produce variations among organisms

• Survive and produce

• Are mechanisms of evolution

Individuals with the most favorable combinations of genes

• Produce variations among organisms

• Survive and reproduce

• Are mechanisms of evolution

As time passes...

• Are mechanisms of evolution

• Survive and reproduce

• Produced variations among organisms

• The unfavorable combinations of DNA 🧬 disappear and the favorable ones remain

For resources and places to live occurs in most species

• Overproduction

• Competition

• Heredity

• Environmental change

The species with the most favorable DNA 🧬 combinations survive the others disappear

• That allow some individuals in a species to survive to adulthood

• Of offspring occurs in many species when they have too many babies

• Heredity

• Adaptations
