There's also certain physical limitations like how big a terrestrial insect could get before it's exoskeleton was too heavy to move.
And it blows my mind how Creationists cannot grasp that evolution is a continuum and not a novel advent with each news species.
BTW, if your avatar is a photo of yourself as mine is, then we look remarkably alike.
First 'rule' of evolution suggests that life is destined to become more complex

This is one of the more interesting aspects of evolution; sexual reproduction. At some point, for every species which reproduces through sex, there had to be a mutation which facilitated the change from asexual to sexual.
Which one are you Jack? The one on the left, or on the right?
I have long been a legend for my unparalleled powers of observation that are only compromised when I spot an opportunity for a weak joke.To save my time in answering that question of the multitude of the curious I placed the answer under the photo where it has remained for several years.

A person clearly demonstrates they don't understand how inheritance works.
Same person proclaims that millions of biologists and geneticists, all of which know 10x more about biology and genetics, are all wrong.
Hmmm, interesting.
Next, this same person will be telling us that God must bestow English onto each American generation because children could not invent English over and over and over each generation.
It is not an intelligence at work but simply a description of reality.
You're the one who wants to restrict the meaning, based on some odd notions about how humans use words.
Sorry, but that's not the meaning of the word "evolution". At all. It's not remotely what I mean by it, and I study evolution for a living.
To a scientist, "random" means having an unpredictable outcome.
In the specific context of evolution, it means "random with respect to fitness", that is, that there is no mechanism by which an organism's need dictates which mutations occur. I am talking about evolution, I'm talking about random mutations -- in the sense that scientists use the term -- and those processes are completely consistent with a divine purpose for evolution.
They forget or perhaps never learned that evolution is what happens to populations not to individuals.
Whether a mutation is beneficial or not depends on the context. Sometimes a mutation can be both advantageous and disavantageous in different circumstances
Circular reasoning. Populations are made up of individuals.
If a crustacean mutates a coat of fur...
If a fox in a chilly climate mutates a hard exoskeleton...
If either of those things happened, evolution would be falsified
Why?
Complexity is a silly concept in this context.First 'rule' of evolution suggests that life is destined to become more complex
March 17, 2008
Scientists have revealed what may well be the first pervasive ‘rule’ of evolution. In a study published in the Proceedings of the National Academy of Sciences researchers have found evidence which suggests that evolution drives animals to become increasingly more complex.
Looking back through the last 550 million years of the fossil catalogue to the present day, the team investigated the different evolutionary branches of the crustacean family tree.
They were seeking examples along the tree where animals evolved that were simpler than their ancestors.
Instead they found organisms with increasingly more complex structures and features, suggesting that there is some mechanism driving change in this direction.
“If you start with the simplest possible animal body, then there’s only one direction to evolve in – you have to become more complex,” said Dr Matthew Wills from the Department of Biology & Biochemistry at the University of Bath who worked with colleagues Sarah Adamowicz from from the University of Waterloo (Canada) and Andy Purvis from Imperial College London.
“Sooner or later, however, you reach a level of complexity where it’s possible to go backwards and become simpler again.
“What’s astonishing is that hardly any crustaceans have taken this backwards route.
“Instead, almost all branches have evolved in the same direction, becoming more complex in parallel.
