While we are on the subject of scientists who don’t even need to do politeness any more while defending classical Darwinism’s teachings on junk DNA (because they are more right than the facts?), it turns out that humans and squid evolved eyes with the same genes:
Eyes and wings are among the most stunning innovations evolution has created. Remarkably these features have evolved multiple times in different lineages of animals. For instance, the avian ancestors of birds and the mammalian ancestors of bats both evolved wings independently, in an example of convergent evolution. The same happened for the eyes of squid and humans. Exactly how such convergent evolution arises is not always clear.
Actually, no one has any idea how it arises.
Cephalopods have a camera eye with the same features as the vertebrate camera eye. Importantly, the cephalopod camera eye arose completely independently from ours. The last common ancestor of cephalopods and vertebrates existed more than 500m years ago.
So how likely is a Darwinian common-ancestry explanation then? Note: The answer “It must have happened that way because evolution is true” will not be graded in a serious modern biology course.
Pax6 RNA splicing in cepahlopods is a wonderful demonstration of how evolution fashions equivalent solutions via entirely different routes. Using analogous structures, evolution can provide remarkable innovations.
So if “evolution” just randomly did this, why don’t we hire “evolution” to solve intractable problems?
Here’s the paper.
