What else can I help you with?
Is all members of species are identical to each other?
Species make up populations and populations make up communities.
Why are there so much variation with a species?
Variation within a species is due to genetic diversity, which arises from random mutations, recombination during reproduction, and gene flow from other populations. This variation provides the raw material for natural selection and enables species to adapt to changing environments.
What is a is a gradual variation in phenotypes and genotypes over a geographic span?
A gradual variation in phenotypes and genotypes over a geographic span is known as a cline. Clines occur when environmental gradients influence the distribution of traits within a species, leading to a gradual change in characteristics—such as size, color, or behavior—across different populations. This phenomenon highlights the relationship between genetics, adaptation, and geographic location, illustrating how populations can exhibit continuous variation rather than distinct categories.
What is the difference between a subspecies and a variety?
A subspecies is a taxonomic rank below species, representing populations within a species that have distinct characteristics but can interbreed. A variety is a taxonomic rank below subspecies, representing populations within a subspecies that have minor differences in characteristics.
What is the definition for variation?
Variation refers to the degree of difference or diversity among individuals within a population or species. It can involve differences in traits, characteristics, or behaviors, which can be shaped by genetic, environmental, and other factors. Studying variation is important in understanding evolution, adaptation, and biodiversity.
What is a result of the limited genetic variation in the current cheetah populations compared to earlier cheetah populations with more variation?
d. current populations of cheetahs are able to interbreed with other species, increasing genetic variation.

Is mango leaf a parallel variation?
No, mango leaf is not considered a parallel variation. Parallel variation refers to easy and reversible changes within a species or population, while mango leaf characteristics are part of the natural variation within the species.
When micro evolution occurs over many generations are inherited characteristics lead to changes in populations what has occurred?
When microevolution occurs over many generations, inherited characteristics can lead to changes in populations. This can result in the adaptation of populations to their environment, leading to the emergence of new traits and the evolution of new species. This process drives biodiversity and is driven by natural selection acting on genetic variation within a population.
Describes why the two minnow populations evolved into separate species?
Different selective pressures were acting upon the two populations, leading to an increase in genetic variation and the formation of two new species. study island
What is clining?
In biological terms it is the change in certain characteristics of populations of organisms of the same species
Which best describes why the two minnow populations evolved into separate species?
Different selective pressures were acting upon the two populations, leading to an increase in genetic variation and the formation of two new species.(study island)

What were the elements for the formation of new species?
The formation of new species typically involves factors such as geographic isolation, genetic mutations, natural selection, and reproductive isolation. These elements contribute to genetic divergence between populations, eventually leading to the evolution of unique characteristics and the formation of distinct species.
Discuss how 1 variation within a species 2 geographically isolated populations and 3 fossil organisms make it difficult to clearly define a species?
what is this, your homework? yes and its hard.
