Your question (and motives) is suspect since you use the term "evolutionary force."
There is no force and the use of the word suggests you do not understand Evolution.
Biological cells randomly mutate at a known natural rate. Biological cells also undergo coerced mutation through the Photoelectric Effect or chemical reaction.
Radionuclides such as Uranium, Thorium, Barium, Lead, Bismuth, Iodine, Strontium and a host of others too numerous to mention exist in rock strata, which through the process of erosion by wind, water, and glacial action, ends up in a stream or creak flowing from a mountain or hill.
Mama bird with embryo
in utero drinks from the creek and and ingests Strontium or something else.
That atom or atoms of a radionuclide will kick off an alpha, beta, gamma or x-ray particle or a fission fragment.
Such a particle with 1 MeV of energy will ionize 30,000 atoms in your body as it zips around.
To ionize an atom means the particle has struck an orbiting electron knocking it and altering the atom in a number of ways.
Should that happen in the gene that controls the color of feathers, it may result in feathers of another color.
So, baby bird is born with red feathers instead of brown feathers.
At that precise moment, the process of Natural Selection begins.
Baby bird will either survive and reproduce passing the "defective" gene that produces red feathers to its off-spring, or it will never reproduce because other birds don't like the red feathers, or a predator will kill it.
That, is Evolution.
Then again, the "defective" gene could be the one that controls the structure of the beak, so baby bird is born with a spoon-bill instead of a pointy beak.
Again, at that precise moment, the process of Natural Selection begins.
Maybe baby bird lives in an environment with muddy or sandy soil and the spoon-bill easily digs into it to provide food. And maybe baby bird reproduces and passes that "defective" gene onto its off-spring.
Or, maybe baby bird lives in an environment with hard or rocky soil and the spoon-bill is totally freaking useless and it dies unless it can find some other way to get food.
Again,
that is Evolution.
Do let us know when you understand.

That suggests you don't understand basic high school biology or chemistry.
When water freezes, it expands in volume. That's how pot-holes form. There's a defect in the road surface, it rains, water rests in the defect, temperatures drop below freezing, the water freezes and expands causing the road material to buckle, fracture, etc.
Mammals, avians, reptiles, amphibians have biological cells that contain water. The water freezes and expands breaking the cell membrane and killing the cell.
That's what frost-bite is about.
For many insects, the exterior integument is not living cells, rather it is a material known as chitin which is mostly Calcium, a mineral and not a biological cell.
If your skin was made of a hard material from Calcium instead of living biological cells, maybe you could be frozen and brought back to life, too.

That suggests a poor understanding of physics and astronomy.
It has been widely known for decades that Earth's axial speed has slowed. It was, at one time, close to 23 hours and not the current 24+ hours.
Might I suggest you toss your library and update it with books from the 20th Century on.

You don't say.
It is also well-established that certain asteroid impacts have slowed Earth's rotation from time-to-time in the past.
Although you may not understand this, gravity is a vector force and the alignment of the other planets can also slow Earth's axial rotation.

You would think that that would put an end to arguments against biological evolution. |
There are none so blind as those who refuse to see.
