Over at Design Matrix, Mike Gene defends the view that “Complex LECA [Last Eukaryoic Common Ancestor] is no tautology”:
Someone with the moniker DrREC replied to my posting about the complexity of the last eukaryotic ancestor as follows:
This is almost a tautology. The last Eukaryotic common ancestor had the defining features of a Eukaryote….which happen to be more complex than prokaryotic life.
There is no tautology at work here. Not even close. We can appreciate this by simply recognizing that scientists could very well have discovered that LECA was remarkably simple. For example, it could have been a cell with a nucleus, but lacking protein-coding introns, mitochondria, golgi bodies, ubiquitin, and flagella. And its nuclear pore complex, cytoskeleton, and endomembranous system could have been rather simple. But as it turned out, LECA had a level of complexity that rivals modern day cells.
In which case, Darwinism is wrong.
We may not know what’s right but we can know that Darwinism is wrong – if it is indeed a theory in science. Which many now seriously doubt.
