Does species diversity follow any patterns?
Does species diversity follow any patterns?
Does species diversity follow any patterns? The diversity of species is lowest at the poles and increases toward the equator, with the deserts being obvious exceptions. Tropical rainforests and coral reefs are among the planet’s richest and most complex ecosystems.
Is there a correlation between evolution and species diversity?
Evolution and diversity result from the interactions between organisms and their environments and the consequences of these interactions over long periods of time. Organisms continually adapt to their environments, and the diversity of environments that exists promotes a diversity of organisms adapted to them.
What is the strongest evidence that there is an evolution of biodiversity?
Comparing DNA Similar DNA sequences are the strongest evidence for evolution from a common ancestor.
Who are the scientists behind the evolution of biodiversity?
Charles Darwin [2] identified the first principle of the origin of modern biodiversity, namely that all species were linked in a single great phylogeny, or tree of life, and that all could be traced back to a presumed single original species at some distant time in the geological past.
What are the 3 patterns of biodiversity?
Darwin noticed three distinctive patterns of biological diversity: (1) Species vary globally, (2) species vary locally, and (3) species vary over time.
Which group of animal has the greatest known species diversity?
Insects are the largest and most diverse group of organisms on Earth. There are approximately 30 orders with the number of described species reaching nearly 1 million. However, some scientists believe the actual number may exceed 20 million!
What causes a species to evolve?
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
What evidence supports the theory of evolution?
Fossil evidence supports evolution. The geographic information about many fossils provides evidence that two species with a common ancestor can develop differently in different locations. An is an early form of an organism from which later forms descend.
What species concept is most useful?
the biological species concept
By far the most well-known species concept is the biological species concept, which was proposed by evolutionary biologist Ernst Mayr. The biological species concept states that a species is a group of actually or potentially interbreeding natural populations which are reproductively isolated from other such groups.
Which country supports almost 10 of biodiversity on the earth?
South Africa
Being one of the most biodiverse countries in the world, South Africa contains nearly 10 % of all known species of fish, birds and plants. It also has a 6 % of the mammal and reptile species registered in the world.
