Progressive politicians' current proposals for reducing inequality.

I think we need more than these. For instance, to stop companies from dodging taxes, and to make large companies break up. We also need public funding for campaigns for office, so that the rich don't have so much influence.

Humans have linguistic capabilities that spoken language does not use. Assuming that spoken language came first, and sign language was used only by the few deaf people, those capabilities must have arisen as a byproduct, without being selected for.

Is it possible that humans developed a sign language first, and only later a spoken language which replaced it? This would simplify the evolutionary path.

If spoken language came first, it required evolving multiple facilities at once: controlling production of a variety of speech sounds, as well as the higher-level organization of them.

However, if humans had already evolved great manual dexterity and the ability to carry out a series movements, for other activities, developing sign language would have required evolving only the higher-level organization.

Spoken language has its advantages: for instance, you can talk to people who can't currently see your hands well, or at all. If humans started using vocalizations as substitutes for certain signs, and supposing this gave them an advantage, they would have encountered selection for control over a broader variety of speech sounds.
