What is a characteristic that improves a individuals ability to survive and reproduce in a particular environment?
having genetic variation among most of its members
What is the process by which the best suited individuals survive in their environment?
The answer of that qeustion is natural selection of which animals produce offspring.
What is the fitness of an organism?
The ability to survive and reproduce
What are Darwin's four postulates?
1. There is variation in individuals within a species 2. Variation ensures that individuals that are better suited to their environment will survive. 3. Traits that assist individuals in survival and allow them to reprduce gradually spread throughout population. 4. Individuals produce more offspring than the local resources can support.
What did Darwin call the ability to survive and reproduce?
Darwin called the ability of an organism to survive and reproduce in its environment fitness.
What is a characteristic that improves a individuals ability to survive and reproduce in a particular environment?
having genetic variation among most of its members
What is the measure ability to survive and produce more offspring relative to other members of the population called?
Fitness is a term that is used to measure the ability to survive and produce the most offspring.
What allows organisms to survive the process of natural selection in their environments?
the unequal ability of individuals to survive and reproduce
What allows natural selection and evolution to occur?
the unequal ability of individuals to survive and reproduce
What is fitness and describe survival of the fittest?
th ability to survive and produce fertile offspring
What is the process by which the best suited individuals survive in their environment?
The answer of that qeustion is natural selection of which animals produce offspring.
What is the measure of the ability to survive and produce more offsring relative to other members of the population called?
fitness
What is the fitness of an organism?
The ability to survive and reproduce
What is the process in which individuals with useful traits are more likely to survive and produce more offspring with those useful traits?
natural selection
What are the 4 key principles of natural selection?
1. Overproduction - more offspring are born than survive 2. Genetic Variation - there is variation in the population 3. Struggle to Survive - organisms with suitable variations will survive and reproduce 4. Differential Reproduction - suitable variations are passed on to offspring
What is a characteristic that improves an organisms ability to survive?
Organisms need an adaptation to improve their ability to survive. For example, a virus 'evolves' (adapts) to flu immunizations, so every year world health organizations such as the United States Centers for Disease Control (CDC) must analyze viruses to identify the strain and any adaptations it made. Then, they develop a new vaccine for that year.
