Bones Began as Mineral Batteries

Today, bones hold us up. But for ancient jawless fishes, bones may have been a way to store energy for long journeys. Plus, new research indicated that hippos and cetaceans may have evolved their aquatic traits separately.

    6:16 Fish knew how to make bones because they knew in advance that they could store nutrients in them. They also knew which nutrients would be beneficial for them to store and they also knew it would be better not to evolve into human beings even though human beings would exist and then subjugate, capture and kill fish. They knew what would be beneficial for them and what would be harmful for them. They knew how to create and change their biology on a macro, cellular and atomic level so that everything went perfectly. They had complete knowledge of themselves and they were all wise. This is what I am understanding from your statement, Hank. This is what your Patreons pay for you to produce.

    Medicine assumes that having ‘high bone density’ is what prevents fractures. With ageing, part of what we lose is our “collagen matrix”. This is what makes our bones ‘bendy’ and resilient during impact such as accidents or falls. This there’s an area that needs more research. The ‘bone builder’ drugs are not actually shown to reduce hip and spinal fractures. I disturbingly high percentage of people who fall and get a broken hip, will never walk properly again. Mortality shoots up in the 1-year window, post injury.

    Why is this called Scishow? No science here, only speculation, imagination, belief. Some facts about existing life biology then the always crazy attempts to tie it to some kind of evolution. Its always that way. Because there is never any proof. In fact modern knowledge of micro and molecular biology proves the opposite, and THAT is science..

      @jaymz1999 My comment is not a suggestion, it is facts, a few of many, that prove evolution is not a fact. Here is the only fact that matters: natural random events cannot generate complex molecules required for life, no matter the scenario. Impossible and that's a fact. No one knows what the first simplest life form was. No one knows how the first carbon based complex molecules came to be. No one knows how they became more complex molecules that interacted with other complex molecules to become functional in some primitive manner. No one knows how that progressed to eventual primitive coded DNA that guides reproduction. No one knows......until that is known and reproduced in the lab, which should be easy given the ideal pristine conditions not found in hostile nature, then virtually everything about evolution is pure speculation. Belief. Not fact. Not knowledge. Like dinosaurs to birds, absurd. Proof that no one knows:
