Author, your findings are dead on, there are however some things you missed. It would actually appear that species are directed to their food, as though there is some type of pre-programming that tells them what to eat. We know this to be fact because we don't hear about species going through an experimental stage where they are eating rock and dirt to find they don't like them. Not to be confused with starving species, which can eat anything and this is a serious clue. Why aren't they eating anything right off the bat?
My observation, and its open to anyone that can prove it wrong. Species appear to know what they are suppose to eat. A very small percentage are shown what to eat by the parents, where does this leave the rest? From what I'm able to figure out, each species is suppose to only eat around one to three things in food. Thus the term target food. This food is ideal in every way to the consumer. It's ideal in nutrition, and vitamins, and will appear to be perfect for the species.
When a species is not subject to target food either because its gone extinct or either had moved location, then the species starts to enter one of three phases of hunger. Phase one can be identified easily because you will see a species eating almost everything within a food group, its as though they are looking for the target food. What we call a food group and what they see as a food group could vary with common sense.
Phase two is where the species would additionally pick up a new food group. This is going to happen when that target food and phase one food, for whatever reason is not available. You can observe the squirrel in wiki with a phase one diet, but then they also list a second diet he turns to when those aren't available,
Phase three is eating rocks and dirt, total starvation. This is where target food, phase one and phase two foods are no longer in reach.
So now your question about humans, and why we seem to eat everything under the sun. It states in the bible that many things were placed on earth, every herb, every plant, and every animal. It also states that none of these things are from our home, yes big surprise, earth is not our home, and that’s a quote. So in other words nothing here is our target food, which also explains why we make some of our own food and process the hell out of a lot of it.
We have no target food, this is the reason why we have so many problems with the food we eat, we have to process the hell out of it, even cooking is a process. Why we have supplements too, because its hard to get a good balanced diet from food that was not intended for you. Yes intended. It would appear that this balance in life is staged and not even the theory of evolution can explain tandem symbiotic food sources. Either way you slice this, there has to be intelligence involved at some point.
You can't even argue that a species goes by personal taste, or smell, or observation, because its a little to odd how everyone in a species always eat the exact same thing, (excluding humans) providing location and access of course. If there was personal choice in these decisions, we would also see an experimental stage, which we also don't find anywhere, again not to be confused with starvation.
Target food actually reveals that there is some type of organized intelligence. There is no way that a species could be programmed with knowing what their food is suppose to be without the programmer first knowing about the food itself. It's something that evolution totally fails at producing. There excuse is that the food evolves along with the species, but that in itself would also require intelligence of some sort. Natural selection
doesn’t appear to afford the answer.
All of the things that were brought to earth have caused a big problem. (Including humans) God went around to different planets and collected life from everywhere, and brought some here to earth, causing an imbalance in our habitat. This is why we are in the 6th largest extinction looking at a loss of 99% of all life as we know it. You can't just remove or add species to a balanced planet, it knocks off the balance. So right now all of the apex predators are winning. This has stumped scientists because they are first making the wrong assumption that all life that is here, belongs here.
There is another problem, we have no natural source for calcium. Humans, not including teenagers and pregnant women need 1000mg a day. The highest item on the list is sardines, and you will still need 5.4 servings a day, or 16 ozs a day. Fruits and veggies do not measure up to what we need. Cows milk is NOT a natural supplement, and it has to be processed to be safe from bacteria as well, however if you choose to go that rout I think 4 servings a day will suit you. Processed cheese is the best, and at the top of the scale is seaweed, 7 to 14 times higher than cows milk, of course it has to be processed as well.
