No, I am saying that you don't have to know how life started, or really what life is, in order to be able to understand and learn from the patterns of life.
All ducks are not the same. Going from one species of duck to another species of duck is macro. The term duck is a casual term that can include members of many different species and several different genera. You are using casual terms to try to describe concepts that must be described in noncasual terms.
I have several .30 caliber rifles. Can I use the same ammo in all of them since they are all .30? After all, a duck is a duck and a .30 is a .30. I would have a hard time trying to shoot some 30/06 out of my .30 Carbine. To the unknowing a .30 should fire any .30 cartridge. That would be a logical assumption. My late uncle claimed I could shoot a 30-30 cartridge out of my 1903 Springfield. To those better informed with the terminology of ammunition the differences between a 30/06 and a .30 Carbine are obvious.
