can someone explain on a theoretical level why microevolution is possible and macroevolution is not? I'm not looking for debate about whether macro happened or not, simply why it's possible for small changes can evolve over small periods of time but it's impossible for large changes to evolve over large periods of time. can anyone enlighten me?

Don't large changes imply strategy to map out the macro environment to attempt and deploy a solution?

No, they don't.

Okay, paint me a picture of what macro evolution looks like.

Microevolution and macroevolution are not terms used by biologists
These are nonsense words repeated ad nauseum by American christcucks to sow public confusion around the topic of evolution.

I'd imagine it's just small changes adding up over many thousands of generations. I don't see how "strategy" plays into a massive random process over the course of millions of years

This isn't what OP ask. OP asked for an explanation of why macroevolution can't happen.

There is no need for a "map", macro is simply many micros one after another. If you want a painted picture take a look at the op.

Then what's macro about it? It's just evolution. Macro infers to a unified scale which is meaningless if there is no rhyme or reason to it at that scale as everything grows from micro.

some agree that microevolution exists since there is indisputable proof of it, but argue macroevolution is impossible for some reason, I just want to know why

we dont know if its possible to explain all large genetic changed as the sum of a bunch of smaller ones.

maybe some can and others cant as the span of a set of mutations may never allow certain dna sequences to exist

They're called crackpots and they used to have zero purchase here.
Now we have election tourist idealist creationist whackjobs armed with youtube links they scarcely understand and abstracts they don't understand at all. Didn't you know we died a death?

Yes. Science is all a power play, right now liberals have the power to make their facts and their knowledge science. Eventually we will recapture the academies and we will then push our knowledge and our facts.

There is "zoom far enough out and micro aggregates to a macro," but we can't say whether or not sporadic large scale changes in sequencing don't occur at certain advantageous intervals.
I once read a paper about hominids developing optic blasts and the ability to walk through walls in seemingly a few generations. Very nicely illustrated. I'll see if I can find it.

>Macroevolution generally refers to evolution above the species level. So instead of focusing on an individual beetle species, a macroevolutionary lens might require that we zoom out on the tree of life, to assess the diversity of the entire beetle clade and its position on the tree.
>Macroevolution encompasses the grandest trends and transformations in evolution, such as the origin of mammals and the radiation of flowering plants. Macroevolutionary patterns are generally what we see when we look at the large-scale history of life.
>It is not necessarily easy to โ€œseeโ€ macroevolutionary history; there are no firsthand accounts to be read. Instead, we reconstruct the history of life using multiple lines of evidence, including geology, fossils, and living organisms.

>Microevolution is simply a change in gene frequency within a population. Evolution at this scale can be observed over short periods of time โ€” for example, between one generation and the next, the frequency of a gene for brown coloration in a population of beetles increases. Such a change might come about because natural selection favored the gene (as shown below), because the population received new immigrants carrying the gene, because of mutation, or because of random genetic drift from one generation to the next.
