Biogeography as evidence that evolution accounts

While public understanding and acceptance of evolution is notoriously low, with fewer than half of adults in countries such as the United States and Turkey accepting evolution as fact J.

Biogeography as evidence that evolution accounts

Introduction[ edit ] The patterns of species distribution across geographical areas can usually be explained through a combination of historical factors such as: Through observing the geographic distribution of species, we can see associated variations in sea levelriver routes, habitat, and river capture.

Additionally, this science considers the geographic constraints of landmass areas and isolation, as well as the available ecosystem energy supplies.

Over periods of ecological changes, biogeography includes the study of plant and animal species in: It also asks Why? These habitats are often much more manageable areas of study because they are more condensed than larger ecosystems on the mainland.

They can then apply their understanding to similar but more complex mainland habitats. Islands are very diverse in their biomesranging from the tropical to arctic climates.

This diversity in habitat allows for a wide range of species study in different parts of the world. One scientist who recognized the importance of these geographic locations was Charles Darwinwho remarked in his journal "The Zoology of Archipelagoes will be well worth examination". During the 18th century most views on the world were shaped around religion and for many natural theologists, the bible.

Carl Linnaeusin the midth century, initiated the ways to classify organisms through his exploration of undiscovered territories. When he noticed that species were not as perpetual as he believed, he developed the Mountain Explanation to explain the distribution of biodiversity.

When Noah's ark landed on Mount Ararat and the waters receded, the animals dispersed throughout different elevations on the mountain. This showed different species in different climates proving species were not constant. Through his strong beliefs in Christianity, he was inspired to classify the living world, which then gave way to additional accounts of secular views on geographical distribution.

This was important to a George Louis Buffon's rival theory of distribution. Wilsona prominent biologist and conservationist, coauthored The Theory of Island Biogeography and helped to start much of the research that has been done on this topic since the work of Watson and Wallace almost a century before Closely after Linnaeus, Georges-Louis Leclerc, Comte de Buffon observed shifts in climate and how species spread across the globe as a result.

He was the first to see different groups of organisms in different regions of the world. Buffon saw similarities between some regions which led him to believe that at one point continents were connected and then water separated them and caused differences in species.

This was inspired by his observations comparing the Old and New World, as he determined distinct variations of species from the two regions.

Buffon believed there was a single species creation event, and that different regions of the world were homes for varying species, which is an alternate view than that of Linnaeus.

Buffon's law eventually became a principle of biogeography by explaining how similar environments were habitats for comparable types of organisms. At the end of the 18th century, Alexander von Humboldt, known as the "founder of plant geography", [3] developed the concept of physique generale to demonstrate the unity of science and how species fit together.Biogeography, the study of living things around the globe, helps solidify Darwin’s theory of biological evolution.

Basically, if evolution is real, you’d expect groups of organisms that are related to one another to be clustered near one another because related organisms come from the same common ancestor.

Evolution: Evolution, theory in biology postulating that the various types of plants, animals, and other living things on Earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations.

It is one of the keystones of modern biological theory. Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological kaja-net.comsms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area.

Phytogeography is the branch of biogeography that studies the distribution of plants. Indeed, virtually all aspects of biology can be viewed in one way or another as providing evidence of evolution.

Evolution is what accounts for the signs of shared biological ancestry that appear throughout our natural world, ranging from anatomy and development, to fossils, to . There is much support for the theory of evolution.

This evidence comes from a variety of scientific fields and provides information that helps us trace changes in species over time. Evidence that supports evolution includes fossil evidence, biogeographical evidence, anatomical evidence and biochemical evidence. Discuss each of these ideas and how they support the .
