The process by which organisms best suited to their environment reproduce more successfully than others
Natural selection
Natural Selection
The process by which organisms best suited to their environment reproduce more successfully than others
Overproduction
Every population is capable of producing more offspring than can survive
Every population is capable of producing more offspring than can survive
Overproduction
Variation
The many differences within every population, some favorable, some unfavorable
The many differences within every population, some favorable, some unfavorable
Variation
Selection
In a given environment, certain traits can make individuals more likely to survive, and more likely to produce more offspring
In a given environment, certain traits can make individuals more likely to survive, and more likely to produce more offspring
Selection
Adaptation
Over time, those traits that improve survival and reproduction will become more common
Over time, those traits that improve survival and reproduction will become more common
Adaptation
Adaptation (2)
An inherited trait that is present in a population because the trait helps individuals survive and reproduce in a given environment
An inherited trait that is present in a population because the trait helps individuals survive and reproduce in a given environment
