Microevolution: what is it?Microevolution: what is it?

Microevolution is evolution on a small scale — within a single population. That means narrowing our focus to one branch of the tree of life.

If you could zoom in on one branch of the tree of life scale — the insects, for example — you would see another phylogeny relating all the different insect lineages. If you continue to zoom in, selecting the branch representing beetles, you would see another phylogeny relating different beetle species. You could continue zooming in until you saw the relationships between beetle populations.

Defining “Populations”Defining “Populations”

For animals, it's fairly easy to decide what a For animals, it's fairly easy to decide what a population is. It is a group of organisms that population is. It is a group of organisms that interbreed with each other — that is, they all interbreed with each other — that is, they all share a gene pool. So for our species of beetle, share a gene pool. So for our species of beetle, that might be a group of individuals that all live that might be a group of individuals that all live on a particular mountaintop and are potential on a particular mountaintop and are potential mates for one another. Biologists who study mates for one another. Biologists who study evolution at this level define evolution as a evolution at this level define evolution as a change in gene frequency within a population.change in gene frequency within a population.

In the case of antibiotic microevolution by natural selection. In the case of antibiotic resistance, for example, a bacterial strain's huge population resistance, for example, a bacterial strain's huge population size and short generation time mean that natural selection size and short generation time mean that natural selection acts quickly. In each bacterial generation, new mutations acts quickly. In each bacterial generation, new mutations and gene combinations are generated. If any of these confer and gene combinations are generated. If any of these confer resistance to a drug to which the bacteria are exposed, resistance to a drug to which the bacteria are exposed, natural selection will favor those gene versions.

Thus God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament; and it was so. And God called the firmament Heaven. So the evening and morning were the second day.

Condensation of matter to form the earth; Creation of the watery planet

Genesis 1:9-13(Day 3)

Then God said “Let the waters under the heavens be gathered together into one place and let the dry land appear;” and it was so. And God called the dry land Earth, and the gathering together of the waters he called the seas. And God saw that it was good. Then God said, “let the earth bring forth grass, the herb that yields seed, and the fruit tree that yields fruit according to its kind, whose seed is in itself, on the earth;” and it was so. . . . And God saw that it was good. So the evening and the morning were the third day.

The appearance of land, and separation from water.

Plants are created with genetic variety.

Genesis 1:14-19 (Day 4)

And God saw it was good. And God blessed them, saying “Be fruitful and multiply, and fill the waters in the seas, and let birds multiply on the earth. So evening and the morning were the 5th day.

All varieties of birds, sea animals are crated with genetic variety and limitations (kind).

Genesis 1:25-31(Day 6)

Then God said, “Let the earth bring forth the living creature according to its kind: cattle and creeping things and beast of the earth, each according to its kind;” and it was so.

Then God said, “Let Us make man in Our image, according to Our likeness; let them have dominion over the fish of the sea, over the birds of the air, and over the cattle, over all the earth, and over every creeping thing that creeps on the earth. So God created man in His own image; in the image of God He created him; male and female He created them. Then God blessed them and God said to them, “Be fruitful and multiply; fill the earth and subdue it; have dominion over the fish of the sea, over the birds of the air, and over every living thing that moves on the earth.” And god said, “See I have given you every herb that yields seed which is on the face of all the earth, and every tree whose fruit yields seed to you it shall be for food. Also, to every beast of the earth, to every bird of the air, and to everything that creeps on the earth, in which there is life, I have given every green herb for food;” and it was so. Then God saw everything that He had made, and indeed it was very good. So the evening ad the morning were the sixth day.

Land animals and insects with genetic variety and kind are created. Man is created in the image of God (the First Cause)
