It's literally impossible.
Obviously not, because it happened and IS happening.
Darwinian evolution relies on random mutations that are selected by a blind, unguided process of natural selection that has no goals.
You guys are so good at ignoring one half of the mechanism (or the other half) when ranting against evolution. It is random mutations AND natural selection combined. You rail against something you don't understand. You may be able to convince yourself that you are correct, but you can't convince a jury. In fact, Evolution has been in front of the courts on many occasions, and the creationists have always lost.

To believe that a random system can get from here to there requires one to leave their common sense behind.
Except it happens; and can be traced back through genetic sequencing; and can be replicated in computer programs.
National Academy of Sciences biologist Lynn Margulis: “new mutations don’t create new species; they create offspring that are impaired."
I take it you do not research the sources of your quotes. I guess that's okay, because in my cursory research, I found anti-Creationist sites that wrote her off as a Creationist, but she is not. Lyn Margulis is an "evolutionist". She holds to a theory called "symbiosis in evolution". While primarily rejected, her work in advancing evolutionary theory eventually won her significant awards, Dawrin-Wallace Medal.
She did not question evolution. She questioned the mechanisms by which evolution happened.
You have quoted an evolutionist to further creationism. How quaint.

By the way: She is also wrong. The vast majority of mutations are completely benign; such as mutations of red hair and green eyes. Every human being has an average of 175 genetic mutations.

Pierre-Paul Grasse: “[m]utations have a very limited ‘constructive capacity'” because “[n]o matter how numerous they may be, mutations do not produce any kind of evolution.”
Pierre-Paul was a proponent of a now discredited theory of evolution called "neo-Lemarkian Evolution" which postulated that an organism's behavior affected traits it would pass to its offspring. He was wrong about that too. And again, he was an evolutionist, not a creationist; so again, you have quoted an "evolutionist" to support Creationism.

The fossil record’s overall pattern is one of abrupt explosions of new biological forms, not transitional forms
EVERY form is a transitional form ... including US. Of course, in spite of the thousands of transitional forms out there, you will ignore them to hold to your narrative, jam your fingers in your ear, and yell, "nya nya nya nya nya!"
