Some individual organisms are better equipped to live and reproduce in their environment than others. If what makes them better equipped is heritable, their offspring will be more numerous and will tend to inherit the same traits or qualities themselves. The opposite will happen to those poorly equipped. They will have fewer or no offspring, and their negative traits will tend to disappear from the population as time goes on. These two tendencies are called positive (natural) selection and negative (natural) selection respectively. Natural selection is always relative to the environment. What is advantageous in one environment may not be so in another, and what is disadvantageous (deleterious) in one environment may not be so in another.

What concept of evolution explains why organisms are constructed to meet the demands of their environment?
Natural selection explains adaptive change in the immediate environment.
Natural selection allows a species to change in response to its environment. What is the process by which a species becomes better suited to its environment called?
Adaptation (I'm studying the same thing ;)
Which type of natural selection in which the mean characteristics of a population are preserved?
This type of natural selection is called stabilizing selection because the mean traits of the population are being selected for against the immediate environment.
How does the theory of evolution disprove the belief that natural selection prepares an organism to adapt to its environment Natural selection occurs before changes in the environment. A population ch?
To begin with, a theory can not prove or disprove anything until it is proven itself.
Is eviromenntal changes drive reprodution a natural selection?
Environment IS natural selection, so a change in environment is a change in selection pressure.

natural selection
How does environment select organisms?
natural selection
What role does the environment play in Darins theory of evolution by natural selection?
The environment is the '' natural selector. ''
Does natural selection cause changes in the environment?
No, natural selection is the environment! The variant organism is selected against the immediate environment where it survives and reproduces better than it's conspecifics.
How can a wide range of phenotypes increase the chance that some individuals will survive in a changing environment?
by natural selection.
Why does the environment act on natural selection?
I know of no government that acts, in any direct or significant way, on natural selection.
What is the degree of adaptation to a specific environment?
Natural Selection.
How did homo habilis change his environment?
Homo habilis altered their environment by creating simple tools from stones and sticks, which helped them improve their hunting and gathering capabilities. They may have also used these tools to modify their surroundings, such as digging for roots or breaking into animal bones for marrow. These adaptations allowed Homo habilis to expand their diet and increase their chances of survival.
