Only one will survive
In an ecosystem, a niche is a very specific role that a species can play in that system. When two species attempt to fulfill this exact same role, their prey becomes much more scarce, and one will eventually force the other out.
This idea was first formulated by G. Evelyn Hutchinson, an ecologist who proposed the concept of ecological niche in the 1950s. The competitive exclusion principle, based on this concept, states that two species cannot coexist if they occupy the exact same niche in an ecosystem.
A single species, or two species that occupy different niches in the same range and use different resources. Darwin's finches are an example of this. Large strong beaks take the large seeds and small beaks take the lesser seeds as resources.
The short answer is that one is always going to be slightly better at that exact niche than the other, and so will drive the competitor to local extinction. In reality, two species in nearly the same niche will often co-occur, but there will be more resources in a very similar niche that will allow for one species to exploit those other resources. Evolution can happen very quickly in these high competition areas (in a matter of a few years, it has been directly measured).
We will never be able to have a person the exact same as us in everyway :(
Only one will survive
When two species occupy the exact same niche, competition between them increases as they vie for the same resources. This can lead to one species outcompeting the other, one species evolving to use different resources, or both species coexisting by partitioning resources or developing specialized niches within the broader niche.

The exact way Species 8472 reproduce is unknown. They have as many as 5 sexes (So not your Standard Male and Female) and all occupy a different part of fluidic space. They do court as evidenced by the Voyager Episode "Someone To Watch Over Me".

Because a niche is an organisms place in an ecosystem, specific to only that organism and including its job and what is eats or is eaten by. Two different organisms can have similar niches, but they cannot have the exact same one.
Because if that species then goes extinct, we have an exact specimen of the species
The exact number is not known, but there are around 3,500 species of plant species in the Namib desert.
The Arabian horses species is the exact same as all other horse breeds. E.Ferus.
The exact opposite happens
All of them 2700 species to be exact.
