They diverged enough so that they can't crossbreed.
Biodiversity describes the different populations that live in a habitat, encompassing a variety of species and genetic diversity within those species. It reflects the richness and complexity of ecosystems.
The four sources of supporting evidence for the theory of evolution are fossils, the development of life forms, changes over life forms over the years and the way in which related species are distributed across the world.
A community is an assemblage of different populations that live together in a specific area. It includes various species interacting and coexisting within an ecosystem.
Different populations that may live in a defined area include human residents, wildlife species, domestic animals, and plant species. Each population interacts with the environment and other populations in the area, leading to complex ecological relationships. Understanding the dynamics of these populations is important for effective land management and conservation efforts.
Biologists call the populations of many species occupying a particular place a community. This term refers to all the different populations of organisms living and interacting in the same area or ecosystem.
Two populations have evolved into two species when the populations can no longer interbreed.Are you answering a question from the Holt Science & Technology: Life Science textbook? Because these questions are my homework. :P
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

A population is a group of one type of species. A community is several different populations together.
Between 300 and 400 living species, depending on how you count. Scientists don't always agree on whether two different-looking populations should be considered as different species, different sub-species, or just different populations. There are of course likely thousands of extinct species that arose and went extinct over the last 70 million years or so since the first primates evolved.
it suggested that over time the species had evolved and adapted to the climate they were in.
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.
populations of different species in the ocean should be monitored so that there is always source of food for the other ocean animals.
When the continent separated some of the same species ended up on different continents. This is because the continent was so large the species were distributed across the continent. So, when it split, some were on one side and others of the same species were on the other side.
Millions of years of evolution
No, humans and dogs have evolved from different ancestors, they are completely different species.
