Coevolution And Evolutionary Responses At First Thought

Evolution: Charles Darwin's theory was that species change over time, or evolve, in response to their environment. A good example of this is the evolution of the Kangaroo. Approximately 55 MYA the kangaroos looked quite similar to a possum and it was a tree dweller with a prehensile tail, but as Gondwana split up, the rainforests disappeared, the climate became hotter and the land dry and arid, the kangaroo evolved along the way and have come to look like what they do now.

Evolution is the change in the inherited characteristic of biological populations over successive generations (Wikipedia). The most notable theory of evolution was Charles Darwin’s speculation about natural selection. Natural selection is the process by which nature rewards those individuals better adapted to their environments with survival and reproductive success, defined by Ker Than, a Senior Editor in TechNewsDaily on livescience.com. Darwin published the first edition of “The Origin of Species” in 1859, in which Darwin theorized how a bear can turn in to a whale by natural selection. "I can see no difficulty in a race of bears being rendered, by natural selection, more aquatic in their structure and habits, with larger and larger mouths, till a creature was produced as monstrous as a whale," Darwin speculated (Than).

The concept or idea that species change and evolve into new and different species was described and was an established concept in Darwin's day this was described as descent with modification. The Concept of descent with modification has major evidence in support, in fact we no longer refer to the this adaption as descent with modification, rather it is now called biological evolution.

Evolution is a theory that is supported with evidence that characteristics of living organisms change over generations. A species can change over time and may even split into two new species through a process called Speciation. Each new species adapts to its new environment through adaptability. This is the ability of an organism to change its physical and chemical nature to adjust to its surroundings. For example, adaptive radiation is a form of evolution that Charles Darwin had discovered.

Coevolution happens when two species evolve together because of the relationship they have with each other. For example, as prey gets faster to avoid being eaten, predators also have to be faster in order to eat. Coevolution can also happen between organisms with a relationship a mutualistic relationship as shown Figure 3. Pollinators, such as hummingbirds, have evolved beaks to feed on specific plants. The plants benefit because they are pollinated.

The Darwinian view of life came into focus in 1859, when he published one of the most important books called “ On the Origin of Species by Mean of Natural Selection”. Back in Darwin’s time in the 19th century historians were being to think of evolutionary change as an explanation for patterns observed in the future. He did not invent this idea however he carried out the necessary research to document the idea. He made this book to make two valid points, “descent and modification” and “process natural selection”. Descent and modification described the evidence and support that he gathered about species. “It is an insightful phrase, as it captures the duality of life’s unity (descent) and diversity (modification).” Simon, Eric J., Jane Reece,

Evolution is the change in heritable characteristics of organisms  over time. Evolution was developed by a man named Charles Darwin in 1859. Charles said that evolution happens over time and when two species split into two. There are two ways that Charles came up with that show evolution , the first one is by Natural Selection. Natural Selection is when some organism are better at surviving than others , like if a giraffe with a short neck and a giraffe with a long neck . The giraffe with the long neck is going to survive longer  because the giraffe with the short neck will not be able to get as much high leaves as the other giraffe. The other  way is by inherited traits , like with the giraffes sense the giraffe with the long neck has more

According to Thompson (1994), coevolution is defined as “the reciprocal evolutionary change in interacting species”. This occurs when one species has a significant effect on the survival or reproductive success of another species and vice-versa, leading to the gradual evolution of both species. It is important to study this topic, as it is possible that the evolution of a majority of the world’s life forms was affected by the coevolution occurring between plants and insects (Smith et al., 2009). It is generally accepted that there are three forms in which coevolution can take place

In science, evolution is one of the basic templates to understand the biology of an organism or ecological unit. Changes in that ecosystem cause adaptations to occur in species, if there is time. With human intervention (pollution, climate change, deforestation, etc.) many species do not have time to adapt, and therefore move to a new environment or become extinct.

Charles Darwin broached the theory of natural selection in his book the Origin of Species, which has been considered the basis of evolutionary biology to this day. Natural selection is when populations of a species evolve over the course of many generations. Darwin believed that species were not created separately, but instead, species were derived from one another. In other words, the evolution of species creates many variations among creatures, and this is because all of those species came from a common ancestor, and characteristics changed to increase the species chance of survival.

Evolution is the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth. According to Charles Darwin’s theory, evolution can occur by means of natural selection. It is the process whereby species become adapted to their environment over generations.

Evolution refers to change over time as species modifies and separate to produce several offspring species.

At its simplest evolution is how information is transmitted over time. Although Charles Darwin did not know about modern genetics with DNA and chromosomes, he did know that organisms resemble their parents, variation in a single species is able to be inherited, and that as there is change in population survival of the fittest will allow only the superior organism to pass its dominance on.(Eldridge 69) Darwin discovered many theories, such as natural selection and the descent of man from a common ancestors with apes, that caused a great opposition because they went against the traditional beliefs of society. Nevertheless, his theories were eventually accepted by the scientific community and they even went on the create the concept of Social

As stated in On the Origin of Species, the Theory of Evolution claims that “… new species in the course of time are formed through natural selection” (Darwin 86). The heart of this theory is descent with modification. This suggests that over countless generations, minute genetic variations have occurred due to mutations. These genetic variations have the ability to alter how a species interacts with its environment. If the genetic variation deems beneficial to the species’ likeliness to survive and reproduce, the mutation will be passed down to its offspring. Through many years of completely random mutations deeming to beneficial, large enough changes occur in a species for it to have evolved into a completely new species; this is where that phrase origin of species comes from in the title of Darwin’s publication. The Theory of Evolution also encompasses common descent, an idea claiming that: “… all living

Biological evolution is the name for the changes in gene frequency in a population of a species from generation to generation. Evolution offers explanation to why species genetically change over years and the diversity of life on Earth. Although it is generally accepted by the scientific community, Charles Darwin’s theory of evolution has been studied and debated for several decades. In 1859, Darwin published On The Origin of Species, which introduced the idea of evolutionary thought which he supported with evidence of one type of evolutionary mechanism, natural selection. Some of the main mechanisms of evolution are natural selection, mutation, and genetic drift. The idea that all life on Earth shares a common ancestor has been around for
