It has happened in as little as a single generation in the case of orchids. Generally speaking, groups of organisms that do not interbreed on on the borders of speciation, whereas those that cannot interbreed are considered to be separate species.
Dromedaries and llamas have been separated by more than ten million years, yet they can interbreed. Humans and chimpanzees are separated by less than six million years, yet it is doubtful our species can interbreed.
It probably depends significantly on the amount of change between groups, but I would estimate most species separated for more than a hundred thousand years would be sexually incompatible.

Why does evolution take a long time?
The reason that evolution takes a long time is because each generation, the offspring are nearly identical to their parents. However, they are slightly different, and thus a few of the individuals are slightly more likely to survive than the others. Then, these individuals spread their genes to just a few more offspring than the others do.Because there is only a tiny difference in how many offspring the more adapted version has, it takes a long time for the more adapted version to completely replace the older version.
How long does the process of natural selection and evolution take?
The process of natural selection and evolution can vary in terms of the time it takes, ranging from hundreds to millions of years depending on the species and environmental factors. Evolution is a gradual process that occurs over generations as populations adapt to their changing surroundings through natural selection.
How long did the evolution take?
The process of evolution has been ongoing for billions of years, with life forms gradually changing and adapting to their environments over time. The exact duration can vary depending on the specific species or traits being considered.
How long does photosynthesis take to occur in plants?
Photosynthesis typically takes a few seconds to a few minutes to occur in plants, depending on factors such as light intensity and availability of water and nutrients.
Can photosynthesis occur with artificial light sources?
Yes, photosynthesis can occur with artificial light sources, such as grow lights, as long as the light provides the necessary wavelengths for the process to take place.
How long did it take for evolution?
To see evolution it take hundred thousand, or tenth of thousand.
How long did it take for it?

What is the main factor that effects the evolution of a star?
The mass of the star affects the evolution of the star. It helps to determine how long evolution will take and what kinds of changes will happen.
How long does it take for mitosis to occur?
it take 12 to 24 hours
Why would evolution take 4.2 billion years?
Evolution doesn't take 4.2 billion years. It takes forever and no time at all. Where life is, there evolution is happening, and it will continue to happen as long as life exists.
Why evolution of man considered as a complex process?
The evolution of man is considered a complex process because it takes thousands of years for even a small change to occur. It is a result of genetics and physiological changes which take many generations to take hold.
In biology evolution means what?
Evolution in Biology terms means a change in a species over a long period of time. It can take several generations for a characteristic in a species to change.
