Why Does Evolution Happen

The theory of evolution is a species will adapt to the environment it is in over generations to ensure they have the desired traits to survive and reproduce. An exceptional example of evolution is the saltwater crocodile, who has gone through up to 200 million years of evolution since the cretaceous period. Adding on to evolution the proof that supports it is the DNA found that links current species with ancient ancestors, geology how species have certain traits that make them perfectly suited to an environment, and direct observations on how a current species si alike to a past species. The theory of evolution is supported by current species for example the saltwater crocodile and many other physical observations. The individual who created

Every living thing on Earth has evolved into its current form over the course of millions of years. The theory of evolution explains how these organisms changed over time through natural selection. Evolution is still controversial within our society because it conflicts with religious beliefs on how life on earth formed.

Evolution is a real thing that happened and is still happening today, there is so much evidence to prove it. We have the fossil record, we know how natural selection works and how and why it happens, and we know how artificial selection works and that we use it all of the time today. There is just too much evidence to call evolution just a theory.

The issues about evolution have been argued for several hundred years. For example, even until now, some religion of the Christian Denomination still refuse to admit the evolution is a fact. However, evolution explains a lot of phenomenon appearing in nature environment. Thus more and more people believe it and think these phenomenon are the evidence! Let us sort out them below:

Evolution is the process by which all species have gradually developed from a singular common ancestor. The evolutionary theory has developed over time; it states that all species (mammals, insects, birds and reptiles alike) all originated from a single celled organism that existed roughly 3.8 billion years ago. The scientific use of the word “theory” proclaims something that is as solidly established as any scientific fact. When using the word theory scientifically, it is defined as an idea that has evidence and fact to back the truth of the assumption. In science, a theory is only true as long as there is no evidence to disprove it 's conclusions. As it is known today, evolution is a theory that explains the diversities, yet similarities between all species that have ever walked the Earth.

Adaptation as defined by Merriam-Webster (2013) is the adjustment to environmental conditions, adjustment of a sense organ to the intensity or quality of stimulation. Synonyms for adaptation: acclimation, accommodation, acclimatization, adjustment and conformation. Charles Darwin theory of natural selection states that organisms adapt to their environment to become better fitted to survive and that they pass these genes on to the next generation ( ). According to Natural Resources Canada (NRC) adaptation includes activities that are taken before impacts are observed (anticipatory) and after impacts have been felt (reactive). Both anticipatory and reactive adaptation can be planned as a result of deliberate policy decisions and reactive adaptation can also occur spontaneously (NRC, 2008).

to HoThru the centuries scientist like Charles Darwin have had their theories of evolution like most scientist believe that life has been on earth for more than 4mo Sapiens. Now there is plenty of evidence that evolution is a real thing like tons of fossils have been found in the earth's crust and they all belong to ancient species including Homo Erectu billion years and that all the ancient species evolved into more highly developed creatures and that most of the animals we see today are descendents of those ancient species. Now evolution is the process that all organism on earth go threw were they better developed into highly intelligent beings and that is exactly how we came to be we human beings went threw evolution billions of years ago now we first started out as Homo Erectus then down the line we evolveds lus there have been cave drawings found all over the world that depicts Homo Erectus and many other ancient species .

The theory of evolution, as set forth by Charles Darwin in 1859, stated that all plant and animal life evolved over long periods of time from simple to more complicated forms through mutation and adaptation. He also taught that only the fittest of each species would survive. He further postulated that the first living cell evolved in a "warm warm little pond" and that it took billions of years for the present diversity of living things to evolve. At the time, it was thought that the few "missing links" in the fossil record would be soon filled.(Darwin, 1927 ). Today, however, there is today a considerable body of scientific evidence that refutes this entire theory.

The origin of modern day whales, a mystery that has puzzled paleontologists for years, may have just been solved with the discovery of an ankle bone. This discovery might sound simple and unimportant, but the bones of these ancient animals hold many unanswered questions and provide solid proof of origin and behavior. The relationship between whales and other animals has proven to be difficult because whales are warm-blooded, like humans, yet they live in the sea. The fact that they are warm-blooded suggests that they are related to some type of land animal. However, the questions of exactly which animal, and how whales evolved from land to water, have remained unanswered until now.

evolution is a biology thing you don't have to believe in it but it happened so dill with it.i'm going to tell you what evolution is based on what i've searched up on it. During and since Darwin's time, people have been looking for and studying evidence in nature that teaches them more about evolution. were used by Darwin to develop his theory of natural selection, and are still used today. Others, such as DNA testing, were not available in Darwin's time, but are used by scientists today to learn more about evolution. Five types of evidence for evolution are discussed in this section: ancient organism remains, fossil layers, similarities among organisms all others, such as DNA testing, were not available in Darwin's time, but are used by scientists today to learn

The theory of evolution is a very interesting, but also a bit of a controversial topic. The Merriam Webster dictionary defines evolution as “a theory that the differences between modern plants and animals are because of changes that happened by a natural process over a very long time.” Even though many people would and have disagreed with this following statement, the theory of evolution as of now is the best the best way of explaining why people and the animals which are, are on earth today.

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 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

Adaptation in biology is when a species becomes adaptable to its environment, as a natural selection and heritage variation. Their structures, physiology, genetics, dispersal, reproduction systems, development and defensive mechanisms are part of the variation and aspects found in these species (Gittleman, 2017).

Adaptation- Dictionary definition of Adaptation (adapted by me) states that it is a process of changes- by means of which any organism or species becomes better suited to live & thrive in its environment.
