Natural selection is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to future generations. It does give individuals with adaptive traits a competitive edge in their environment, increasing their chances of survival and reproductive success compared to those without these traits.
For natural selection to occur, C. There must be limited resources in the ecosystem is true. Limited resources create competition among individuals for survival and reproduction, leading to the selection of traits that enhance fitness. Additionally, variation among individuals and the ability to pass on advantageous traits are also essential for natural selection to drive evolutionary change.
It's mainly mutations in the DNA and recombination of chromosomes that produce the genetic variation. Natural selection then favors those changes that give rise to greater reproductive success.
yes natural selection takes place without human control. In natural selection it is the environment selecting the traits/alleles. However there is something called artificial selection which is evident in dog breeding. In that case humans select for the traits. Artificial selection can have detrimental effects on a population though. Some dogs have been selected for being very small and having a flat nose. These dogs are so small now that they cannot give birth naturally and have no use of their nasal passages
For natural selection to occur in a population, there must be variation in traits among individuals and differential survival and reproduction based on those traits. This means that some traits give individuals a better chance of surviving and reproducing in their environment than others, leading to changes in the population over time.
Mutation, a copying error in the replication of DNA, can give rise to variation in an organisms phenotype and if this new phenotype is beneficial to survival and reproductive success ( as little as 1% ) it will be selected naturally against the immediate environment, then if this so selected organism leave many descendents with the same beneficial traits then the populations gene pool will change in allele frequency and you have evolution. ( a 19th century sentence Darwin would be proud of! )
Drugs, in some cases, give them a competitive edge.
No, our ability to drive automobiles is not a trait that has evolved through natural selection. Driving is a learned skill and is not influenced by genetic traits that are subject to natural selection.

Artificial selection is when humans select traits, such as color or taste and breed for those traits. Natural selection chooses the creatures that are best able to give birth to more offspring, carrying on their genes. The environment chooses.

Cows that give more milk than other cows are an example of selective breeding for increased milk production. This process involves choosing cows with desirable traits, such as high milk production, and breeding them to pass on these traits to future generations. Over time, this can lead to a population of cows that consistently produce more milk than the original population due to genetic selection.
Because in the wild there is a struggle for existence as more organisms are born than there are resources to support them. Thus, there is a wide variety of traits expressed by these many organisms and some of these traits confer survival and reproductive advantages which is what natural selection is selecting for.
When Homo Sapiens came along, Neanderthals and Cro-Magnons died out.
If the information being shared gives another individual an unfair advantage or competitive edge, it is considered to be confidential or proprietary information. Sharing such information can lead to unethical practices and may violate agreements or laws related to trade secrets. This is often seen in business contexts where competitive integrity is crucial. Protecting such information is essential for maintaining fairness in the market.
AOL/Time Warner has a competitve edge because it maintains control of a lot of important and influential companies.
