Creation Moment 2/2/2020 - When Scorpions Sting Evolution

"A press release from the Ohio State University News, the academic
home of one of the co-authors of the paper, wrote that the scorpion they call a “prehistoric animal” lived “about 437 million years ago.” It had “respiratory and circulatory systems … almost identical to those of our modern-day scorpions.
The dating method used to claim the 437-million-year age of the creature was described as follows:
we date things with ash beds — and when we don’t have volcanic ash beds, we use these microfossils and correlate the years when those creatures were on Earth. It’s a little bit of comparative dating.
Thus, from their own words, assuming their hodge-podge dating method is correct, this scorpion respiratory system has not changed in 437 million Darwin years!
A few differences were found, including some that are unique compared to all modern arachnids, namely a pair of large lateral compound eyes and a higher number of sternites in the ventral exoskeleton.
The only two ‘primitive’ traits in these fossils (compound eyes and seven mesosomal sternites) have “nothing to do with aquatic or terrestrial adaptation.”

The author added that “researchers found that the animal likely had the capacity to breathe in both ancient oceans and on land.” This, she explains, helps scientists understand “how animals transitioned from living in the sea to living entirely on land.”
The challenge of evolving a terrestrial system from an aquatic system is solved, in her thinking, if scorpions evolved a two-function respiratory system over time. They could use the aquatic system first, while one for the terrestrial environment evolved in parallel.

Problem is, it is widely acknowledged that evolution cannot be goal-directed toward future conditions. Each change must provide a selective advantage immediately. In this case, there would be no selective advantage until the terrestrial system evolves that is both functional and beneficial for the survival of the organism.

There’s another problem in these scorpion fossils. Their so-called ‘ancient’ respiratory and circulatory systems are
almost identical to those of our modern-day scorpions—which spend their lives exclusively on land — and operate similarly to those of a horseshoe crab, which lives mostly in the water, but which is capable of forays onto land for short periods of time.
In other words, P. venator could apparently breathe both in land and in water.
Q: Does this fact help scientists understand how life evolved from aquatic to terrestrial life?
A: No; it only indicates how an organism can live both in water and on land – something very different. What is required is evidence of a progression from aquatic life to exclusive terrestrial life. An animal that does both is not evidence of a respiratory system evolving from water to land."
