What is the barrier preventing a shared ancestry between taxonomic families? If the barrier works at that level, then why does it not work on say, speciation?Hold on now! No sweeping generalizations, please.
Your judgement about me is wrong… I base my pov on evolution regarding the empirical evidence, not on suppositions.
Which means, I actually believe quite a lot of the evidence, of how species change, ie., evolve, over time.
But the specific phenotype characteristics that posits these species within their respective family level of taxa, I.e., what separates the felidae from the canidae…I see no relationship at all. Such assertions are based on inference, not solid evidence. The first in these families, were created. Their descendants then gradually evolved into more species.
When scientists include terms such as “probably”, “could have”, or “likely”, those are suppositions… those scientists have left science, and entered the realm of philosophy.
Good question!
So the shared characteristics of Coleoptera, Lepidoptera, Diptera and Hymenoptera indicating shared ancestry are all an illusion? That is at the level of the order above families. If you look at the basic body plan of insects, it is shared through the entire class. So what exactly was created? The basic insect that evolved into many orders, families, genera and species? That is what the evidence indicates. Still looking for that barrier that is preventing evolution of higher level taxa?
