Evolutionary Ancestors and Just-So Stories
People may tend to think that evolution describes the origin of man from apelike ancestors, and that part does get a great deal of attention, but there is more to it. When biblical creationists use expressions like molecules-to-man evolution, it is not an exaggeration.
Sciences and evolution use a prairie schooner-full of abbreviations, one of which is LUCA: last universal common ancestor. This was not some critter, but even further back in the realm of imagination. Remember biology classes? It led to prokaryotes and eukaryotes, and then more acronyms.

As part of the evolutionary model, evolutionists must explain the origins of complex life-forms, including eukaryotic life. According to the model, there was a single common ancestor of all life that eventually developed into the prokaryotes and eukaryotes we have today. The first eukaryote then developed into the wide variety of eukaryotes we see today. Since there are approximately 8.7 million estimated species of eukaryotes on earth, the evolutionists have a lot of explaining to do.
