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.
How could the evolution of a characteristic within one species affect the evolution of a characteristic within another species?
A simple coevolution explanation here. A population of rabbits that is running faster, on average, over time is going to affect the population of foxes that pursue the rabbits as food. Some foxes will have variations that lead to faster running and these foxes will be the ones that are reproductively successful and give rise to following generations of foxes.
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.
Why do characteristics usually vary within a species?
Characteristics vary within a species due to genetic diversity. This diversity arises from the combination of genes passed down from parents to offspring, leading to variations in traits such as size, color, and behavior. These variations can provide advantages in adapting to different environments and are essential for the survival and evolution of a species.
What is a type of diversity that includes all forms of genetic information?
Genetic diversity encompasses the variety of genes within a species or population, including different alleles, gene variations, and genetic traits. It is essential for adaptation, evolution, and overall species resilience.
Which Biological change over time accounts for the diversity of species. This diversity?
The process of evolution through natural selection accounts for the diversity of species over time. It involves genetic variation within a population, competition for limited resources, and differential reproductive success of individuals with advantageous traits, leading to the adaptation and divergence of species.
What three patterns of biodiversity did Darwin note?
Darwin noted three patterns of biodiversity: 1) species vary globally, with different species in different regions, 2) species vary locally, with different species in different habitats, and 3) species vary over time through the fossil record showing gradual changes over long periods.
What mechanisms of evolution decreases the genetic diversity as a species?
Genetic drift, founder effect, and population bottlenecks are mechanisms that can decrease genetic diversity in a species. These mechanisms result in a reduction of variation within a population due to random events that affect the genetic makeup of the population.
Define biological diversity?
Biological diversity refers to the variety and variability of living organisms and ecosystems found on Earth. It includes genetic diversity within species, species diversity within habitats, and ecosystem diversity within landscapes. This diversity is important for ecological balance, resilience, and the functioning of ecosystems.
What is the gradual accumulation overtime within a species?
evolution
What is the advantage of diversity within species?
Diversity within species increases the chances of survival in changing environments because different individuals may have traits that are better suited for specific conditions. It also enhances genetic variability, allowing for adaptation and evolution over time. Additionally, diversity can lead to a healthier population by reducing the likelihood of diseases spreading.
What account for the diversity of millions of species on earth?
The diversity of millions of species on Earth is mainly due to evolution through natural selection, where genetic variations within populations lead to different adaptations to specific environments over time, resulting in the emergence of new species. Additionally, factors such as geographic isolation, environmental changes, and ecological interactions also contribute to the diversification of species.
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.
The new combinations of alleles produced by crossover events help to generate genetic?
diversity within a population. This genetic diversity provides the raw material for natural selection to act on, ultimately driving evolution and adaptation within a species.
