It is the distribution of various species over geographically isolated areas that supports the hypothesis of common descent. For instance, most or even all the indigenous species on geographically isolated islands will bear the closest resemblance to species living on the closest mainland shores, suggesting that they have a relatively recent common origin.
What else can I help you with?
What are three ways isolation occur?
1. When new species form.2. When a group is separated from the rest of its species.3. When members of the isolated group can no longer mate with the rest of species.
What do you call the geographic region of plants and animals where certain species evolve?
That geographic region is called a "biogeographic region." This term refers to areas with distinct ecological characteristics that support the evolution of specific plant and animal species.
How does the geographic distribution of large flightless birds support Darwin's theory of evolution?
The geographic distribution of large flightless birds, such as ostriches, emus, and kiwis, supports Darwin's theory of evolution by illustrating how species adapt to their environments through natural selection. These birds evolved independently on different continents, reflecting the influence of isolation and varying ecological niches. Their similarities in size and flightlessness suggest a common ancestor, while their distinct adaptations highlight how species evolve in response to local conditions. This pattern of divergent evolution aligns with Darwin's ideas about adaptation and speciation.
How does geographic distribution of species around the world support the theories of evolution?
Let us take the marsupials of Australia as a case in point. Geologically we know how long Australia has been a separate continent and from this we can deduce the diversity of life in Australia is the result of isolation and natural selection carrying the organisms of Australia to a certain uniqueness in the world. New information on continental drift just adds to our understanding of this Australian evolutionary process. Many animals, marsupials, have their analogues in organisms in other places in the world.
What types of evidence did Darwin use to support his theory of changes over time?
Individual organisms differ, but some of this variation is heritable. Species alive today are descended with modifications from ancestral species that lived in the distant past.

How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
What are some advantages and disadvantages of isolation?
Advantages of isolation include giving individuals time for self-reflection and promoting independence. However, isolation can also lead to feelings of loneliness, depression, and a lack of social support. It is important to balance time spent in isolation with opportunities for social connection and support.
Which geographic factors increase species richness biodiversity?
Geographic factors that increase species richness and biodiversity include habitat diversity, such as the presence of varied ecosystems (forests, wetlands, grasslands), which provide numerous niches for different species. Additionally, larger geographic areas tend to support more species due to greater resource availability and environmental gradients. Proximity to the equator also plays a role, as tropical regions typically harbor more species due to stable climates and high productivity. Lastly, geographical barriers, like mountains and rivers, can create isolated habitats that lead to unique evolutionary paths and increased biodiversity.
What argument did Darwin support about the beak size and shape of Galapagos finch species and its relationship with something else?
Darwin argued that the different beak sizes and shapes of the Galapagos finch species were adaptations to different diets. This was evidence to support his theory of natural selection, where organisms with traits better suited to their environment are more likely to survive and reproduce.
How does the geographic distributions of different animals support Darwin theory?
