No.
These examples have all been changes within a species.
You may be wondering how species give rise to different species.
This puzzle is much harder to understand because, unlike the examples above, we cannot observe species evolving from one to another. The time scales are usually far too long.
Usually.

There are various ways to define a "species" (and we will come to that in a later lesson). One way to define a species is as a group of plants or animals that are reproductively isolated from another group. That means a species cannot breed outside its own species. If we accept that as a definition then we can "create" a new species and it is particularly easy to do with plants.

Lets consider polyploidy in plants.
Polyploidy means "lots of chromosomes" and colchicine is a chemical that interferes with the number of chromosomes passed to the next generation. So, colchicine can cause polyploidy.

The primrose is a common garden plant in the Genus Primula. There are many species of primrose but two are relevant to this story - Primula verticillata and Primula florbunda. Both have 18 chromosomes each and by crossing them you can produce a hybrid plant that also has 18 chromosomes. These hybrid Primula are infertile. (Most hybrids are infertility. The mule, a cross between a horse and an ass, is a good example of an infertile hybrid.) Plants, unlike animals, can often be "forced" through this infertility by adding colchicine. The colchicine allows unusual numbers of chromosomes to be passed along as gametes. When colchicine was used on the Primula hybrids they produced "healthy" gametes and were able to be crossed amongst themselves to produce a new polyploid Primula with 36 chromosomes. This new species is called Primula kewensis and it cannot breed with either of its parent species (Primula verticillata or Primula florbunda) but it is very capable of producing healthy offspring from its own kind.
This fits our definition of a new species.
This "trick", of using colchicine to move a hybrid through its infertility and create a new species with a different number of chromosomes, is now a common agriculture and horticulture technique for creating new artificial species.

But does polyploidy happen in nature?
Yes, it does.
Colchicine helps the experimenter and moves evolution along quickly but there are natural agents in the environment that will produce polyploids and fertile hybrids. (As a matter of fact, colchicine is extracted from some species of plants!)

Many families of wild flowers are composed of species that consist of simple multiples of a basic number of chromosomes.
By looking at the number of chromosomes in groups of related species, it is possible to guess which originated from polyploid hybridisation. We can then recreate the event in the laboratory.

For example, the mint Galeopis tetrahit has a set of chromosomes that appear to be the addition of the chromosomes from two other mints Galeopis pubescens and Galeopis speciosa. When these two species were crossed the "new" species created is able to breed successfully with the wild Galeopis tetrhit.

It is estimated that 70-80% of angiosperms (plants with hard seeds) are the product of natural polyploid evolution.

Polyploidy is common amongst plants but usually not involved in the speciation of animals. However, there is plenty of evidence of speciation amongst animals and one particularly common and easy to study group of animals lend themselves very well to studies in evolution because they have so many species.
Take a guess as to which of these groups of animals have the most species.
