If everything is exactly the same, there is a lower chance of evolution occurring; diversity is not necessary, but it works quicker. This is because where random mutation is the only thing to introduce wider genetic diversity, it will take a longer time than simply mixing the gene pool up.

Which statement best explains the significance of meiosis in the process of evolution within species?
Meiosis takes place in sexual reproduction and genetic variations takes place in sexual reproduction. Genetic variations lead to evolution to new species.
How does the theory of evolution explain variety within species?
The General Theory of Evolution posits that change occurs not only 'within' a species, but also 'across' species. In this way, change is actually unlimited in the sense that, given the right circumstances and given the right environmental pressures, any form of biological life could eventually be pushed from one species to another. A lizard could be pushed into the form of a bird; a whale could be pushed into the form of a wolf. So, as we take a look at the General Theory of Evolution (AKA Macroevolution)
What is Biological evolution is used to explain?
A gradual development of life forms over time.
How did Darwin come up the theory of evolution?
Darwin did not define evolution as such. What he became famous for after his voyage on the Beagle in the 1830s was defining the pressures that contribute to the ongoing survival of a species within its environment. This later became coined as 'natural selection' and is still regarded today as one of the most important contributions to biology.
What are the three levels of biological diversity?
The three levels of biological diversity are:Genetic diversitySpecies diversity, andCommunity and ecosystem diversity.
What three patterns of biodiversity did Darwin note?
Divergent Evolution, Convergent Evolution, and Coevolution
What is the subject of the book The Edge of Evolution?
The Edge of Evolution: The Search for the Limits of Darwinism is about the evolution and that it can produce changes within species, but there is a limit to the ability of evolution to generate diversity, and this limit (the "edge of evolution") is somewhere between species and orders.
Species diversity is the number of?
species of all six kingdoms living within an ecosystem.
What is the gradual accumulation overtime within a species?
evolution
Why is crossing over advantageous to species?
Crossing over provides genetic diversity, which means many different characteristics are given to individuals of a species. Therefore, if there is more diversity within that species, there is a higher likelihood of that species surviving, growing, and reproducing.
What is the variety of genetic material within a species or population is called?
Genetic diversity refers to the variety of genetic material within a species or population. It includes different gene variations and DNA sequences present within individuals of the same species. Genetic diversity is important for a species' ability to adapt to changing environments and for the overall health and resilience of the population.
What are the three measures to life's variations?
Adaptation: The ability to adjust to changing environmental conditions. Diversity: The range of different species and genetic variations within an ecosystem. Evolution: The process of natural selection and genetic change over time that leads to species' adaptation to their environment.
Give three types of biodiversity essential in preserving ecological systems and functions?
Three types of biodiversity that are essential in preserving ecological systems and functions are genetic diversity, species diversity, and ecological diversity. Genetic diversity is a measure of the variety of versions of the same genes within individual species. Species diversity describes the number of different kinds of organisms within a community or ecosystem. Ecological diversity means the richness of complexity of a biological community.
What are the divisions of evolution?
Evolution is sometimes described as macro-evolution, which is the long-term evolution of an entire new species, and micro-evolution, which is largely to do with less significant evolutionary changes within a species. Many creationists accept the existence of micro-evolution, but say that macro-evolution does not occur.
What is the advantage of diversity within species?
The advantage is that if there is a change in the environment - climate change, new pathogen, etc. - more diversity makes it much more likely that some members of the species survive.
A genetic change which can effect a species fitness?
evolution within a species. the allele frequencies in a gene pool of a population
A key concept in the modern theory of evolution explains?
how variations occur within a species
