What you say is irrelevant. What you need to use is what science says, otherwise you are only creating and spreading misinformation and confusion. Learn the science and use the scientific terms as they are defined by the science, not some made up garbage.
...microevolution is evolution that occurs within a genus - which includes speciation (I think I've got that right). ...
Nope you got it very wrong. Microevolution is evolution that occurs within a
species, and that is where all evolution occurs:
The process of evolution involves changes in the composition of hereditary traits, and changes to the frequency of their distributions within breeding populations from generation to generation, in response to ecological challenges and opportunities for growth, development, survival and reproductive success in changing or different habitats.
Breeding populations are by the scientific definition of species composed of one species. There can be multiple breeding populations for any given species, but only one species in a breedng population.
Macroevolution is the evolution of one genus into another genus, ...
And still wrong. Macroevolution is the evolution of one (parent) species into another (daughter) species, this occurs in two ways:
(1) The process of lineal change within species is sometimes called phyletic speciation, or anagenesis.
and
(2) The process of divergent speciation, or cladogenesis, involves the division of a parent population into two or more reproductively isolated daughter populations, which then are free to (micro) evolve independently of each other.
This results in gradual change over time, increased diversity and nested hierarchies.
... and any evolution above the level of genus.
There is no evolution above the level of species:
The Theory of Evolution (ToE), stated in simple terms, is that the process of anagenesis, and the process of cladogenesis, are sufficient to explain the diversity of life as we know it, from the fossil record, from the genetic record, from the historic record, and from everyday record of the life we observe in the world all around us.
This theory is tested by experiments and field observations carried out as part of the
science of evolution.
If a species is observed to change over generations (anagenesis), we can predict that it will be due to (a) changes in the expressed hereditary traits (genes, morphology, development), (b) that the changes were either neutral or improved the survival and reproductive success of individuals in response to their ecological challenges and opportunities and (c) that if they improved the fitness of the carriers that it will spread within the breeding population in following generations.
This has been observed.
If a clade is observed to form (cladogenesis), we can predict that it will be due to (a) reproductive isolation between daughter populations and (b) independent evolution (anagenesis) within each daughter population. We can also predict the formation of the clade will fall within a nested hierarchy pattern.
This has been observed.
These predictions can be tested again and again against the fossil record, the genetic record, the historical record, and the everyday record of life we observe in the world all around us. Biologists have been testing this theory for 150 plus years, and thus far they have confirmed that the
process of evolution, and the further
process of speciation, are sufficient to explain the diversity of life as we know it.
