Human and Natural Resources
A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than do other individuals because of those traits.
A man-made selection, makes crops, livestocks animals, and pets often bear little resemblance to their wild ancestors.
Is the environment and all kinds of organism around you. We are all connected in an enormous most complex ecosystem which is the original source of all life called Earth.
the number of different species and the populations of each species that exist in a specific area.
the complexity in physical geography including climate. The differences in physical geography can establish the variety of communities or ecosystems.
the genetic variability that organisms inherit from their ancestors which can be passed on their offspring within species.
Process of natural selection
This unequal ability of individuals to survive and reproduce will lead to the accumulation of favorable traits in the population over generations.
Individuals whose inherited traits give them a higher probability of surviving and reproducing in the environment and tend to leave more offspring than do other individuals.
Individuals with beneficial adaptation are more likely to survive to pass on their genes to their offspring, Camouflage is an example of evolutionary adaptation.
Environmental pressures lead to differential reproduction within a population.
Over time, there is a change in allele frequency within the population.
Key Features of Natural Selection
If an environment changes, or if individuals move to a new environment, natural selection may results in adaption to these new conditions, sometimes giving rise to a new species
Which traits are favoured depends on the context in which a species lives and mates.
