Sympatric speciation
Definition
A speciation in which new species evolve from a single ancestral species while inhabiting the same geographic region.

Sympatric speciation is more common in plants. For instance, parent plants produce offspring that are polyploid. Hence, the offspring live in the same environment as their parents but are reproductively isolated. Another example is the rare sympatric speciation in animals, such as the divergence of resident and transient Orca in the northeast Pacific. These two groups of Orca occupy the same habitat but are avoiding each other and they do not interbreed. They have different diets, vocal behaviour, and social structures.
This speciation phenomenon most commonly occurs through polyploidy, in which an offspring or group of offspring will be produced with twice the normal number of chromosomes. Where a normal individual has two copies of each chromosome (diploidy), these offspring may have four copies (tetraploidy). A tetraploid individual cannot mate with a diploid individual, creating reproductive isolation. Sexual selection occurs when a subset of a population chooses to mate with each other only because of specific distinguishing morphological characters or behaviors. Intrasexual competition, is when individuals of the same sex compete with one another for mates and is also referred to as male-male competition.
According to genetic data, about 100,000 years ago, a few species of cichlids reached Lake Victoria from other lakes and rivers and quickly evolved into about 600 species.
For the cichlids, it is hypothesized that the original colonizers adapted to different food sources, providing one source of variation.
So Basically:
When an offspring comes out with double the chromosomes,
it is not normal and therefore cannot mate.
Because of this, it is kicked out of many "homes"
and cannot find a date.
And although they are all in the same place,
they might not have the same face,
so they avoid each other and act differently,
because they are a different race.
Artificial Speciation
Artificial speciation takes place in science labs and is conducted by biologists. The most common example of artificial speciation is the domestic sheep species created by hybridisation, which is the process of mixing two different species together to create a hybrid. This is achieved through lab experiments, where scientists mostly research insects like fruit flies, and in animal husbandry. Animal husbandry is the care and breeding of livestock (animals). Many agricultural products, such as dairy, meat, and wool, depend on animal husbandry
So Basically:
The lab coat people create,
in an increasing rate.
A mixture of two,
and people depend on what they do.
Hours in the lab to create the perfect few.
Thank you lab coat guys for the lovely treat,
of giving us better and more to eat! :D
