Second, the true claim of evolution is that, like I said, changes accumulate over time to create new species as descendants of common ancestors no longer interbreed. It’s not that flies evolve to bats, but flies evolve to specialized flies that can’t create a lineage of offspring.

I see you are posting the limits of evolution.

OOOOOkkkkkkk… macro-evolution as we all know does not mean lineage splitting with loss of function.

You do not get to define your own words. Macroevolution has a standard scientific definition, and speciation is included.
The claim of macro-evolution is that a fruitfly will ultimately mutate into a bat or something much greater.

Your sources are lying to you again. The claim is that bats and fruitflies both evolved from a common ancestor which millions of years ago. Your ill-informed sources mean that your arguments fail because you are not criticising evolution, but some straw-man that your lying sources are feeding you.

You are like a critic of Christianity who fails to understand the Trinity and says that Christianity has three gods, not one. That criticism fails because it is based on a strawman. Your criticisms of evolution fail for the same reason.
 
What limits? “Species accumulate mutations in response to selective pressures which result in new species being formed” is nothing new. It’s the foundation of evolutionary biology. Each specialized species is subject to selection, which drives further evolution.

Single-celled lifeforms ingest metabolic bacteria. These bacteria provide a lot of energy for low (name removed by moderator)ut. This creates mitochondrial cells.

Some mitochondrial cells mutate a set of instructions to encase the free-floating DNA in a protective membrane, creating the eukaryotes.

Some eukaryotes begin living in colonies with other eukaryotes and lose certain abilities in order to specialize into others for the good of the colony, creating multicellular life.

Some multicellular organisms have cells that specialize into information storage and transmission. These individuals proliferate widely due to their increased individual activity.

Some brainy individuals begin to evolve larger internal organs and lose their exoskeletons in favor of fully internal support structures, creating fish.

Some fish move further towards land, and as a result, species that have lungs move onto land and begin nesting in the water, creating amphibians.

Some amphibians evolve genes which create a more rigid shell surrounding their eggs, allowing them to move further inland to new environments. This creates reptiles.

Some reptiles evolve changes in their skulls which change their jaw structure to separate the nasal cavity and mouth, creating synapsids.

Some synapsids, after the Permian Extinction, slowly decrease their size to reduce their water and food intake. After life begins to proliferate again, they specialize as night hunters in order to avoid dinosaurs, which are their natural predators. These become mammals.

After the cretaceous extinction, mammals proliferate across Earth. Some move to Africa. Over time, these mammals respond to their arboreal habitats by using claws as hands and tails as grasping features, becoming primates.

Some grassland primates begin using upright postures in order to see predators above the grass. Those with smaller hips more suited to this new posture survive to pass on their genes, slowly moving towards Australopithecines.

Australopithicenes lose their fur and adapt to their savanna environment, with sweat glands and larger lungs and brains. These are humans.

This is a drastically over-simplified process of human evolution, and details have probably been lost in the process, but this is how the theory of evolution postulates humans came about. Not flies to bats, but fish to amphibians to reptiles to synapsids to mammals to flying mammals to bats.

yup, that is the story without empirical evidence and why it is a theory, a failed theory.

read the posts - it was just an illustration.

An illustration of your lack of knowledge of what the theory of evolution actually says. As I said, you persist in criticising a strawman and using Humpty-Dumpty arguments.
 
Can this be taught?

Genome guardians stop and reel in DNA to correct replication errors​

On the DNA assembly line, two proofreading proteins work together as an emergency stop button to prevent replication errors. New research from North Carolina State University and the University of North Carolina at Chapel Hill shows how these proteins – MutL and MutS – prevent DNA replication errors by creating an immobile structure that calls more proteins to the site to repair the error. This structure could also prevent the mismatched region from being “packed” back into the cell during division.
