Scientists have unearthed an early Cambrian fossil that displays the creature’s nervous system. What makes this find significant?

years,
half a billion years ago the arthropods were perfecting their nervous systems. The arthropods were perfecting the cell types and structures that form the core of our human nervous system today– and todays insects as well. In fact all animals.
An analogy might be that an insect is a little country farmhouse, and a human is a McMansion. They are both still built with wiring and if you spray them with something that poisons and dissolves copper the little country farmhouse will die first, but I will bet you that the McMansion will not be doing too well.
If you want to poison yourself spray insecticides around.
And I have a rhetorical question for you all. Why do you think that neem oil kills insects.
I have a further observation. There are some insecticides that are mechanical not toxic. bT toxin is one of these mechanical insecticides. The last I knew it was believed that the bT crystals disrupted the insects intestinal track.
Now it is simply inconceivable that a crystal that disrupts an insects digestive system will affect a human being and give them irritable bowel syndrome (IBS) right? Regardless a crystal that affects an insect’s digestive system is somewhat unlikely to have neurological effects in a human in my opinion. But using neurotoxins in insecticides is… insane.
