Explanation:
The Knights of labor was the largest and one of the most important American labor organizations of the 1880s. It was founded on the 28th day of December in year 1869 by Uriah Stephens. They promoted the producers ethic of republicanism and demanded the eight-hour day, rejected socialism and anarchism and encouraged the social and cultural uplift of the workingman. In 1880, the organization reached 28,000 members and even gained more members to 100,000 in 1884. But in 1893, the knights of labor declines its membership because of public pressure, power vested in reformist factions, and employers' unwillingness to arbitrate.
People need to believe they have equal social and political rights, else there would be mass protests, revolutions and anarchy. Whether they actually exist in real life is irrelevant here, only the belief matters.
The primary difference in the social structures of humans and animals is the forced imposition of order in human society, leading to a more 'collective' society, instead of the usual 'survival of the fittest/law of the jungle' structure.
And the concept of equal rights is necessary to achieve this imposition of order.
In my opinion, a human society following 'law of the jungle' would be unsustainable, simply because humans as a species are too weak to survive as individuals. The greatest strength of our species is our mental faculty. This leads to the sum of the parts being greater than the whole. As individuals though, we would fail to harness this strength.
Therefore, equal rights do offer us an evolutionary advantage, since they allow us to cluster together, and grow as a population, which is the only way for us to survive.
