How dose natural selection produce adaptations in a species?

Answers

For natural selection to occur, several premises must be satisfied. Firstly, there must be variation in a population. If all individuals are the same, there is no variation on which selection can occur. Secondly, these traits must be heritable, meaning they are passed from parent to offspring. Natural selection cannot operate on traits that have no genetic basis. There must also be differential reproduction, which means that some individuals must reproduce more than others. When all of these factors occur, natural selection results in evolution as advantageous traits propagate throughout the population.

Natural selection is quite variable, as changes in the environment impact what traits are advantageous in a particular time and place. A good of example of this comes from Galapagos finches. These birds have varying beak sizes. Wide beaks are best for eating hard seeds, while long narrow beaks are more adept at exploiting the fleshy fruit from trees. Typically narrow beaks are more prevalent, but during drought conditions when trees cannot produce fruit, seeds become a more abundant food item. This results in those finches with wide beaks having more food available and reproducing more than those with narrow beaks. When droughts persist over many years, wide beaks replace narrow beaks as the most common, but this trend reverses when droughts end and fruits once again become available.
When there is a natural selection upon any species this means that that specific species has an adaptation / a increase in survival skills .

There a Giraffes for EXAMPLE : one group of giraffes have medium length necks and the 2nd group has longer necks , so they can reach the 85 foot tall trees.

That was an example of natural selection , i hoped that my answer helped yo out a lot , have a nice day. 

 

PLEASE HELP ME Write a fictional story illustrating the future effects of global climate change? please 3 pages.

Answers

You can also write about a person living in a new ice age about 20 to 50 thousand years from now, the ice age being triggered by the increased amount of fresh water from the melting Arctic icecaps slowing down the Gulf Stream from Mexico to northern Europe, thus cooling it significantly.
While writing 3 pages if of course a bit of a strech, I can give you some ideas on what you could write about. You can use these ideas then to write your whole essay through them. We know that global warming is happening and that the effect will probably be very severe if we don't do anything against it. Rising oceans which would be a direct consequence to less ice on the poles (warming) and would overflood all the major cities at low altitutes are a good way to start your plot :).

A convex upward fold is referred to as an anticline, and a concave upward fold is referred to as a syncline. In contrast, a synclinorium is a big syncline on which tiny folds are superimposed, while an anticlinorium is a massive anticline.

What Anticline and Syncline act as landforms?

Anticlines are folds that are curved upward to generate ridges, while synclines are curved downward to form troughs. Typically, anticlines and synclines are constructed of numerous folded rock units. The nose is the end of a fold.

The downwards arc or curve of a fold is known as a syncline. In geology, a fold is a bend in a rock stratum brought on by forces deep inside the earth's crust. Folds are brought about by a variety of factors, from small variations in crustal pressure to significant collisions of tectonic plates.

Therefore, A. Anticline B. Syncline
