The diversity of sexually reproducing species is a result of the fact that a) gene pools change over time (by selection and genetic drift) and that b) reproductive isolation occurs, leading to the inability of the descendants of formerly interbreeding subpopulations to interbreed (speciation).

The two factors contributing to the diversity of species?
The two main factors contributing to the diversity of species are evolution and environmental conditions. Evolution leads to the development of new species over time through processes such as natural selection and genetic variation. Environmental conditions, such as climate, geography, and habitat diversity, play a crucial role in shaping the distribution and adaptation of species.
What are the two processes that determine the world's current biodiversity?
The two main processes that determine the world's current biodiversity are speciation, where new species arise through evolution, and extinction, where species die out due to various factors such as changes in the environment or competition with other species. These two processes continuously shape the diversity of life on Earth.
Why are climate and location the two most important factors in determining ecosystem diversity?
Climate and location are important factors in determining ecosystem diversity because they influence the type of plants and animals that can thrive in a particular region. Climate affects temperature, precipitation, and seasonality, which in turn determine the species that can live in an area. Location, such as proximity to mountains, oceans, or deserts, also shapes the availability of resources and habitats for different species.
What two aspects of a community does biodiversity measure?
Biodiversity measures the variety of species present in a community as well as the genetic diversity within those species.
What is gause's competitive exculsion principle?
Gause's Law states that when all other ecological factors are constant, two species competing for the same resources will not coexist. In the long term one will gain advantage and dominate the other, leading to extinction or a behavioral shift in the dominate species' competitor.
Why does extinction endanger diversity?
Extinction is the permanent removal of a species which decreases bio-diversity. Bio-diversity is measured in two fashions # of species and # of members/species these two factors together make up a regions bio diversity, therefore with the removal of a species the regions bio-diversity decreases.

What two factors contrtbute to your individuality?
Social factors contribute to diversity because people have different backgrounds.Individual factors contribute to diversity because people have different personalities.
What are the uses of the Simpson diversity index?
The Simpson diversity index is used to quantify the biodiversity of a community by taking into account richness (number of species) and evenness (relative abundance of each species). It is commonly used in ecology to compare diversity between different habitats or over time. A higher Simpson index value indicates a more diverse community.

What are the two most important factors in determining ecosystem diversity?
Sexual reproduction mixes the genetic inheritance for each generation;Different environmental pressures on different species - only those species that have the best characteristics to survive the environmental pressures will survive long enough to reproduce and leave their genes for the next generation.
What process accounts for species diversity?
Meiosis accounts for species diversity. Meiosis results in four rather than two daughter cells, each with a haploid set of chromosomes. Meiosis is responsible for producing gametes or sex cells.
What two aspects of a community does biodiversity measure?
Biodiversity measures the variety of species present in a community as well as the genetic diversity within those species.

What are two main factors of diversity?
Two main factors of diversity are ethnicity and gender. Ethnicity encompasses the cultural, racial, and national backgrounds of individuals, influencing their perspectives and experiences. Gender diversity refers to the representation and inclusion of various gender identities, including male, female, and non-binary individuals, which can impact workplace dynamics and decision-making. Together, these factors contribute to a richer and more inclusive environment.
What two factors do geologists take into account when they determine earthquake risks?
water
