What describes why the two minnow populations evolved into separate species?
The two minnow populations likely evolved into separate species due to geographic isolation, genetic drift, and natural selection. Over time, differences in their environments caused genetic mutations to accumulate in each population, leading to reproductive isolation and the establishment of distinct traits that are better suited to their respective habitats.
How does reproductive isolation increase the diversity?
Reproductive isolation limits gene flow between populations, allowing genetic differences to accumulate over time. This can lead to the development of new species, increasing biodiversity within an ecosystem.
What happens to the diversity after fragmentation?
Fragmentation can lead to a decrease in genetic diversity within populations and increase isolation between populations which can then decrease overall species diversity in an area. This can result in reduced resilience to environmental changes and increase the risk of local extinctions.
Why does geographic isolation cause specilation?
It prevents the two populations from interbreeding - APEX
How does reproductive isolation increase isolation?
it stops gene flow
Which increase speciation?
Geographic isolation Low geneflow.
Which increases the rate of speciation?
Population bottlenecks Reproductive isolation Niche availability
What would most likely increase the rate of speciation in a population?
Factors such as geographic isolation, environmental changes, genetic mutations, and selective pressures can increase the rate of speciation by driving populations to evolve separate traits or behaviors that lead to reproductive isolation.

How does reproductive isolation increase diversity?
Reproductive isolation prevents gene flow between populations, leading to the accumulation of genetic differences over time. This can drive the divergence of populations into distinct species, increasing overall biodiversity. By maintaining distinct gene pools, reproductive isolation allows for new adaptations to arise and for evolution to proceed in different directions.
How did geographic isolation affect the Kabob squirrel?
Geographic isolation significantly impacted the Kabob squirrel by limiting its genetic exchange with other squirrel populations, leading to distinct adaptations suited to its specific environment. This isolation often results in unique physical and behavioral traits, as the Kabob squirrel evolved to thrive in its particular habitat. Over time, such isolation can also increase vulnerability to environmental changes and reduce genetic diversity, making the species more susceptible to extinction.
What caused the greatest increase in diversity of life during the corse of evolution?
The greatest increase in diversity of life during evolution was likely due to the process of speciation, where one species diversifies into multiple new species over time. This can be driven by various factors such as geographic isolation, genetic mutations, and natural selection acting on different populations.
What happens to the diversity after fragmentation?
Fragmentation can lead to a decrease in genetic diversity within populations and increase isolation between populations which can then decrease overall species diversity in an area. This can result in reduced resilience to environmental changes and increase the risk of local extinctions.
Why does geograpical isolation increase differences between gene pools?
Because they produce with whomever they want which gives them more varieties in a gene pool
Why does geographic isolation cause specilation?

How does reproductive isolation increase isolation?
