Divergent evolution essay

Another popular idea is evolution, the idea that all living organisms descended from a less complex organism. We need to increase our capability to process unstructured data and to move to geographically disperse database in order to move content closer to our customers to improve the customer experience.

Table of Contents Types of Evolution Evolution over time can follow several different patterns. While Google is known for making it easy for any person to search any topic and find their answer, it takes a lot of behind the scene work to run this powerful search engine The changes in beak shape and size were believed to be required to support their change in diet.

Predators or their absence, changes in the environment, and the time at which certain animals are most active are chief among them.

divergent evolution vs convergent evolution

The second principle is natural selection, better known as "survival of the fittest. A lot of research will be put in the development of the device which utilizes the latest technology. Any genus of plants or animals can show divergent evolution.

Similarities between convergent and divergent evolution

We need to increase our capability to process unstructured data and to move to geographically disperse database in order to move content closer to our customers to improve the customer experience. There are many examples of divergent evolution in nature. If only one structure on the organism is considered, these changes can either add to the original function of the structure, or they can change it completely. Share Transcript Divergent evolution occurs when related species develop unique traits due to different environments or selective pressures. It is similar to divergent evolution in that the species descend from the same ancestor, but it differs in that the trait is the same while in divergent evolution the trait is not. Resources Books Merrell, David J. The mobbing behavior was originally developed to protect ground-level nests containing young from various predators such as reptiles, mammals and other birds. Technology is also growing rapidly, thus we are continually influenced and pushed to find new alternative options. Huskies and wolves share similar coat patterns as well as tolerance to cold. In addition, the product will not only be able to detect explosive devices but also landmines that are mostly found in war torn areas especially Iraq and Afghanistan We share a lot of common characteristics but we also share what are called homologous structures. Structures that are the result of convergent evolution are called analogous structures or homoplasies; they should be contrasted with homologous structures, which have a common origin. This happens because the two new species or the two related species are under the influence of different environments or under the influence of different natural selective pressures. Reference Terms from Wikipedia, the free encyclopedia Convergent evolution In evolutionary biology, convergent evolution is the process whereby organisms not closely related not monophyletic , independently evolve similar traits as a result of having to adapt to similar environments or ecological niches. Ridley, Mark.

We've got a rib cage, they've got a rib cage. An example of convergent evolution is the development of horns in various species for sparring over mates, resources, and territory [9] Divergent versus parallel evolution[ edit ] Parallel evolution is the development of a similar trait in species descending from the same ancestor.

An example can involve the diversity of floral types in the orchids. They lived on varying diets and had beaks that differed in shape and size reflecting their diet.

Divergent evolution essay

The tympanal ears of certain nocturnal insects are believed to be a result of needing the ultrasonic hearing that tympanal ears provide in order to hear predators in the dark. Huskies and wolves share similar coat patterns as well as tolerance to cold. In the desert, the heat makes it difficult for animals to eliminate body heat. If only one structure on the organism is considered, these changes can either add to the original function of the structure, or they can change it completely. Therefore, we must expand our thinking abilities in order to survive. Evolutionary relay refers to independent species acquiring similar characteristics through their evolution in similar ecosystems, but not at the same time e. Our upper arm and a bat's upper limb share same bones etcetera even though they're used for different traits, different purposes.

It is similar to divergent evolution in that the species descend from the same ancestor, but it differs in that the trait is the same while in divergent evolution the trait is not.

Parallel evolution occurs when two independent species evolve together at the same time in the same ecospace and acquire similar characteristics extinct browsing-horses and extinct paleotheres.
