Competition is the driving factor in the evolution of organisms. The ones who are least fit (have the inferior DNA for surviving) will be outcompeted and will die before reproduction is possible, or will not be able to provide for their offspring. Therefore, their genetic material will be destroyed. Only the strongest organisms (best DNA) will survive, reproduce, and pass on their information. Therefore, a random mutation in one's DNA that causes it to have a beneficial trait that allows it to outcompete other organisms in the community will survive, pass on its DNA and cause the loss of other weaker animals' DNA.

Why are adaptations evidence of evolution?
Adaptations, such as structural changes or behavioral traits in organisms, are evidence of evolution because they reflect the process of natural selection acting on heritable variations over time. Organisms that possess advantageous adaptations are more likely to survive and reproduce, passing these traits on to their offspring, which can accumulate and lead to changes in populations or species. This gradual accumulation of adaptations is a key mechanism of evolutionary change.
Why would you not expect a fossil buried millions of years ago to look exactly like modern-day organisms?
Nothing sexual reproduces perfectly ... a side effect of evolution. The "fossils" of single celled organisms can look exactly the same, even over a billion years.
What effect did climate change have on the evolution?
Climate change can cause various effects. It causes living organisms to move from their natural habitat.
What effect does tectonic plates have on organic evolution?
The climate because the shifting of tectonic plates will create mountains and vallies overtime, affecting organic evolution.
An example of the founder effect?
The Amish population in the United States is an example of the founder effect. When a small group of individuals established the Amish community in the 18th century, they brought with them a limited genetic diversity. This has resulted in a higher frequency of certain genetic disorders within the Amish population due to the founder effect.
Do humans have a effect on the evolution of the organisms on earth?
no
What role do organisms play in their evolution?
Evolution is the effect caused by the interaction of organisms and their environment, organisms and other organisms, organisms and their genes, and so on. The simplest answer to this question is that organisms produce and propagate replications of the alleles they carry: they reproduce.
The by-product of the metabolism of cyanobacteria that had the most effect on the further evolution of life is?
Oxygen. Cyanobacteria were one of the earliest organisms to produce oxygen as a by-product of photosynthesis. This oxygenation of Earth's atmosphere had a profound impact on the further evolution of life, leading to the diversification of aerobic organisms.
What are three abiotic parts of a marsh community?
Three abiotic parts of a marsh community would be water, climate, stones, and soil. These all effect the living organisms in the marsh community.
How does competition effect an ecosystem?
Organisms all want the same resources.
How do Describe two ways in which the evolution of organisms can have a harmful effect on humans.?
Evolution of certain bacteria can lead to antibiotic resistance, making infections harder to treat. Additionally, evolution of pests can result in decreased crop yields and food shortages, impacting human food supply.
Why do mutations that occur in the skin or nervous system tend to have little effect on the evolution of a species?
Most mutations that occur have a neutral effect, or none at all, so they would not affect evolution. Organisms with mutations that cause detrimental impact typically will not survive; therefore, they will not reproduce, and the mutation will not be passed on, so the species will not be affected overall. Beneficial mutations are typically the only mutations that will affect an organism's posterity and the evolution of its species, but good mutations are very rare. This is why most mutations have little effect on the evolution of a species.
What effect does competition have on price and why?
Competition will lower the price of products
Why are adaptations evidence of evolution?
Adaptations, such as structural changes or behavioral traits in organisms, are evidence of evolution because they reflect the process of natural selection acting on heritable variations over time. Organisms that possess advantageous adaptations are more likely to survive and reproduce, passing these traits on to their offspring, which can accumulate and lead to changes in populations or species. This gradual accumulation of adaptations is a key mechanism of evolutionary change.
How do films effect the wider community?
what are the things effect on the wide community
A random change in a population's allele frequency?
Evolution is the change in allele frequency over time in a population of organisms. By mutation, genetic drift, gene flow and natural selection.
Why would you not expect a fossil buried millions of years ago to look exactly like modern-day organisms?
Nothing sexual reproduces perfectly ... a side effect of evolution. The "fossils" of single celled organisms can look exactly the same, even over a billion years.
