A pair of identical twins can be born, where one ends up eating meat and the other becoming vegan, or one is a wealthy billionaire and the other works in a bar. Genetics is only a framework. Just because you are born with a particular code, doesn’t make you more likely to survive. Survivors can adapt their behaviour to match the code of the existing world.
Earth’s ecosystemsHow ecosystems function An ecosystem is a community of lifeforms that interact in such an optimal way that how ecosystems function best, is when all components (including humans and other animals) can persist and live alongside each other for the longest time possible. Ecosystems are fuelled by the energy created by plants (primary producers) that convert the Sun's heat energy More became more predictable and cyclical, thanks to animals being able to reorder energy into recognisable structures and patterns. For example, an animal finds its food where it expects, because it was involved in cultivating it. The simplest example of this, is how grazers deposit nutrientEnergy and nutrients are the same thing. Plants capture energy from the Sun and store it in chemicals, via the process of photosynthesis. The excess greenery and waste that plants create, contain chemicals that animals can eat, in order to build their own bodies and reproduce. When a chemical is used this way, we call it a nutrient. As we More (droppings) to fertilise food plants, plus their activity pruning the vegetation, increases its nutrient-content and diversity.
There is no direct DNA blueprint for this existence trait, there is only the interaction between the outside world and the animals’ brains. The most likely animal to survive, is one that is born into a world that has been made most suitable for it, by its predecessors.
Think about what you do all the time. You tidy up, move furniture, mow your lawn. You are in a constant strive to alter your own mentality and behaviour by physically changing your outside environment, trying to keep it aligned with what your brain needs. You’re absorbed by your bubble of existence through the inherent need to minimise disorder(Of energy and ecosystems). Ecosystems are thermodynamically driven. Disorder occurs when energy dissipates and becomes more chaotic. For example, the release of hot air into the atmosphere results in that energy is freer to disperse (maximum entropy). The opposite is true when energy is locked into biological processes, when it is stored inside molecules (minimum entropy). Stability in ecosystems occurs More (to make your life easier) and that is what enables you to survive.
Animals, like us, have gradually altered the world by changing its structure into something that suits us best, all the while monitoring what was going on, altering our actions so the real world around and the virtual world inside our brains, are running in parallel.
The longer an environment is without its animals, the higher the risk it won’t be suitable for them. If you try to reintroduce species into habitat that has been without animals for a long time, you won’t achieve a stable ecosystem, because the animals haven’t had long enough to re-integrate their behaviour back into the system. It would be like trying to run old software on a brand new operating system … we all know how frustrating it is, when we update our computer and the old programs don’t work any more.
