Assuming you mean evolution. Virtually every living species on this planet has evolved over time and the fossil record demonstrates this to an amazing degree.

Describe an example of how natural selection influenced the evolution of a particular species?
a great example is the peppered moth. look up the full story in wikipedia
What explains how variations can lead to changes in a species?
variatio brings about evolutionary change with in species as over millions of years the have to adapt to the ever changing habbitats. take the horse for example millions of years ago it used to have multiple toes.yet over millions of years it has evolved to only have one toe
What is non-adaptive evolution?
According to the way most people think about evolution, species evolve because they are becoming more adapted to their environments (natural selection). This is adaptive evolution. Evolution, however, can also happen for reasons other than natural selection. For instance, sexual selection often has little to do with adaptation to the environment (in many species, the colors or loud calls of males attract females for mating but also attract predators; a sexual advantage often does not correspond to an environmental advantage). Sexual selection impacts evolution but has nothing to do with adapting to the environment.The classic example of nonadaptive evolution is genetic drift, in which sheer chance leads to changes in the frequencies of alleles. Evolution occurs because the frequencies are changing, but the alleles are not changing for any reasons of adaptation; it is just random luck.
Is evolution directional?
No, evolution is not directional as the definition is; the change in allele frequency over time in a population of organisms. Google barnacle to see that evolution has no particular direction, but the adaption of the organism to the immediate environment.
Is limited resources discourage the evolution of species true about evolution?
No. It is merely one of many parameters that influence the direction of evolution, and can actually be a driving force in evolution. For example, the rise of warm-blooded mammals as a result of colder climate (a clear period of limited food resources) caused by climatic or astronomical phenomena, like the impact of a meteor.
People with one sickle cell allele are not likely to get a malaria what is this an example of?
It is an example of Natural Selection, Modern Theories of Evolution.
Give five example of common?
evolution. the fossil record. uniformitarianism. the origin of new species. natural selection.

Is a frog an example of natural selection?
No, a frog is not an example of natural selection itself. Natural selection is a mechanism for evolution that acts on populations of organisms over generations, influencing the traits that are passed on to the next generation. Individual organisms like a frog can be impacted by natural selection, depending on their traits and how those traits affect their survival and reproduction.
What is an example of micro evolution?
You are an example of human micro-evolution as the population of humans has changed allele frequency over time. Micro-evolution is just evolution; change over time.
Does the term pioneer have to relate to a person?
Yes it does. For example, "She pioneered the student graduate scheme" or "Charles Darwin pioneered the natural selection theory of evolution"
Darwins theory of evlution?
Darwin's theory of evolution, also known as natural selection, proposes that individuals with traits better suited to their environment are more likely to survive and pass on these traits to their offspring. Over time, this results in a gradual change in a species, leading to the adaptation and evolution of organisms to better fit their environment. The theory has been widely accepted and forms the foundation of modern evolutionary biology.

According to the way most people think about evolution, species evolve because they are becoming more adapted to their environments (natural selection). This is adaptive evolution.

What is an example of micro-evolution?
An example of micro-evolution is the development of antibiotic resistance in bacteria due to natural selection. When exposed to antibiotics, bacteria with genetic mutations that provide resistance to the drug survive and reproduce, passing on the resistant trait to future generations. Over time, the proportion of resistant bacteria in the population increases, leading to the evolution of antibiotic-resistant strains.

If a colony of bacteria were to give rise to an amoeba what would this be an example of?
This would be an example of transformation through evolution. Over time, genetic mutations and natural selection can lead to new species arising from common ancestors. In this case, the amoeba would have evolved from the bacteria through a series of genetic changes.
