By the theory of evolution, new species form through the process of natural selection. This process most often starts with a random mutation in the genome (a random gene suddenly changes or becomes a "mutation"). This mutation either helps, or hinders the new animal (or mutant if you will hehe). If it helps them survive better than the older species, then this new mutant species will become more abundant. If not, than the new species will die off.
This process does not happen all at once though, it usually takes a generous amount of mutations and thousands of years for this to happen.
Pioneer species. They are important for colonizing and stabilizing new habitats, paving the way for other species to establish themselves.
Invasive species are mainly transported and introduced to nonnative areas through human activities such as international trade, travel, and agriculture. They may hitch rides on ships, vehicles, or cargo, or inadvertently be released or escape into new habitats.
Species don't simply "appear" all the time. The development of new species takes thousands of years. According to the theory of evolution, (which mind you, is a theory and not a law) if you take two identical pairs of birds (a male and female) and release them in two very different environments, in several thousand years, (assuming the birds survive the new environment) the birds might have decendants of very different colors, or shape, or diet. Cross breeding is another way, taking two species of the same kind of animal (Two species of fruit flies) and having them mate might produce a new kind of animal Ligers are a cross between a lion and tiger, and yes, they do exist
Adaptive radiation is a rapid form of speciation that takes place when there is a mass immigration to new ecological niches, or a mass extinction of one dominant life form opening up niches for other life forms. Darwin's finches are examples of the former, as they reached the Galapagos Islands as one species and radiated from there into many different species of birds make there living in various ways that called for morphological changes, basically in beak size and shape. The death of the dinosaurs is an example of the latter radiation event. That is when several types of small mammals radiated out into all the niches left open bu the dinosaurs.
It increases the biodiversity of the species.
natural selection
Geographic isolation is a way in which a new species can form. Isolation over a long enough period of time can result in a species evolving to have different traits.
your mom, it's always the answer!
There is one way that new species can develop. The only way a new species can develop is from mating.
The plural form of "species" is "species." It remains the same in both singular and plural forms.
Because new species form every single day which adds more to what scientists know. By the way, Did you know there are hundreds of species of animals out there that scientist have not yet discovered.
Being born is the main way, if you ask me.
Being born is the main way, if you ask me.
Yes there is a new species called Sabbir it is the worlds fattest species they normally way 10 tonnes and there bigger than a London bus.
The main way individuals are added to the population (with animals) is the birth of new offspring.
First, you must a have a population of the same species. They must split so that they cannot cross-breed, this can happen by an island or a canyon range. Then, through many generations mutations, genetic drift, gene flow, natural selection and bottleneck effect comes a new species.
Yes, they can. It happens quite often (comparatively speaking; evolution of new species can take millions of years) and is the major way of new species arising. For example, Darwin's finches were originally the same species, but because of the separation across the Galapagos Islands, they developed differently to the point they became unique species.
