The idea of acquired characteristics. For instance. The idea that a blacksmith, who would develop enormous muscles due to his trade, could pass these physical attributes on to his children.
"Inheritance of acquired traits", one of the implications of this would be that if an individual broke a bone and it did not heal correctly then that individual's children would likely be born with this "new acquired trait" of that bone already broken and improperly healed instead of having a normal bone in that location.

Yes, Galen believed that the jawbone was made of two bones, which he discovered through the dissection of an animal. However this is incorrect as Vesalius later discovered through human dissection that humans only have one jawbone.
He proposed that the biological process of adaptive change over time was driven by an internal desire or motivation within the organism to achieve a goal, e.g., long necks in giraffes. He also incorporated the concept of group selection into his version of evolution, which was later discredited by Darwinism. Individuals always die faster than groups so natural selection will always operate on the individual before the group. Darwinism and current gene centred evolutionary theory has also demonstrated that adaptive change over time is driven by the environment and chance.
To get a 'good' headset you'll have to train the horse to hold it's head in the position you want it to. But you should note that a horses conformation will ultimately dictate how a horse carries itself. Trying to force a horse into an 'incorrect' frame for it's conformation will lead to health issues later on.

The ideas of descent with modification are based on fossils and the modern organisms he found basically says that genetic changes are inherited by later generations.
Atoms revolve in fixed orbit is incorrect. Later, concept of orbitals was given.
