Answer:
Directional selection
Explanation:
Natural selection is of three types :
1. Stabilizing selection: in this type of selection, genetic diversity decreases as the population stabilizes on a particular trait value. Here the mean phenotype is favored.
2. Disruptive selection is a type of selection in which extreme values for a trait are favored over the mean values thus increasing the genetic variance by favoring two extreme phenotypes.
3. Directional selection is a type of selection in which a single phenotype is favored which is of the extreme phenotype over the mean phenotype.
In the given case it can be observed that the selection is favoring long necks in case of giraffes and hence, this is an example of directional selection.
Answer: First off, this makes us dependent on something that is finite. Non-renewable resources such as fossil fuels will eventually run out due to the fact that the dead organisms that have been undergoing the process of becoming carbon (more or less) for millions of years won't have anything to replenish them. Along with that, environmental problems occur like we all are seeing in the United Kingdom and even in the US.
