What is meant by greater fitness in darwinian evolution?
Better adaptions in the immediate environment leading to greater reproductive success. All organisms in a population are variations and in the immediate environment some organisms are better suited to survive and reproduce against their conspecifics. They have greater fitness.
What is home surrounding?
Home surrounding is the immediate environment of the home including events, circumstances, scenery, conditions, people and objects.
What determines which traits in a population are favorable and which are unfavorable?
The immediate environment winnows all variations and some match that environment favorable.
How does survival of the fittest work?
The fit are those in the immediate environment that have the adaptions that cause them to survive and reproduce more successfully than their conspecifics.
How do modern scientists explain the appearance of new traits within a species?
Simply mutation and natural selection against the backdrop of the immediate environment.
What is an immediate environment?
In marketing, the immediate environment refers to the company, competition, and corporate partners. In an immediate environment, the company itself is the first factor that affects a consumer.
How do organisnms evolve?
They change their alleles ( different molecular forms of the same gene ) over time due to naturally selective forces, among others, to shape their morphology and behavior into new adaptions in the ever changing environment by just responding to the immediate environment.
How will you treat your immediate environment?
with respect
What are Immediate effects of depletion on environment?
The immediate effects of depletion are UV entering. They cause plankton death.
How environmental factors contribute to evolution by natural selection.?
Environmental factors ARE evolution by natural selection. The immediate environment is the selector of the organisms that are differentially successful against the immediate environment.
What part of the nucleus controls adaptations?
The genetic material in the nucleus, the two alleles, can change in frequency and this change can change the protein product of the genetic material thus causing a new adaption to the environment. This is all under the natural selection pressure of the immediate environment of course, so anything in the nucleus, such as the genetic material, does not " control " adaptions so much as responding to the selection pressure of the environment on variant organisms in populations.
Contrast immediate and ultimate causes of behavior?
Immediate Cause is the oraganism's interaction w/ the environment and Ultimate Cause is the oraganism's evolutionary.
What is a heat stroke?
