Biology textbooks tend to present evolution as an increase in complexity over time. However, a recent article in Nautilus takes issue with this view.
DNA sequencing technology shows that the trend is not as evident as scientists used to believe:
“Now, DNA analyses are rearranging evolutionary trees, suggesting that the arrow scientists envisioned between simplicity and complexity actually spins like a weather vane caught in a tornado.”
Recent research actually shows that animals “might have been genetically complex from the start … complex body parts evolved multiple times and had also been lost. One study found that winged stick insects evolved from wingless stick insects who [sic] had winged ancestors. Another analysis suggested that extremely simple animals called acoel worms—a quarter inch long and with just one hole for eating and excreting—evolved from an ancestor with a separate mouth and anus. Biologists’ arrow of time swung forward and backward and forward again.”
In other words, the evidence does not support the Darwinian scenario at all. What it suggests is that from the very beginning living beings have been more complex than Darwinists have assumed and that there is far more variety in the animal kingdom than Charles Darwin or his successors ever dreamt of.
It suggests that animals were designed to be complex.
