Answer:
Also called Darwinian fitness, means the ability to survive to reproductive age find a mate, and produce offspring. Basically the more offspring an organism produces during its lifetime the greater its biological fitness.
Explanation:
<span>The chaparral is characterized by sparse, rough terrain and nutrient-poor soil meaning that no single resource is overly abundant. Therefore, a varied diet allows an animal to make use of a wider selection of the resources that are available to it and thereby thrive.</span>
Answer:
subsistence agriculture
Explanation:
The land is limited, cultivation systems are basic, and there is not enough harvest to sell.
Darwin reasoned that natural selection organisms had adapted to new environments, giving rise to new species. It is a principle of speciation.
<h3>Speciation, natural selection and environment</h3>
Different environmental pressures (e.g. the type of food) lead to different evolutionary pathways in genetically related organisms.
The organisms subject to different environments evolve as a consequence of natural selection in order to adapt (adjust) to their corresponding environments.
In consequence, this process may eventually lead to speciation due to the emergence of reproductive isolation barriers.
