Whales and dolphins lead 'human-like lives' thanks to big brains, says study
[In] a new study, researchers compiled a list of the rich behaviours spotted in 90 different species of dolphins, whales and porpoises, and found that the bigger the species' brain, the more complex – indeed, the more "human-like" – their lives are likely to be.
This suggests that the "cultural brain hypothesis" – the theory that suggests our intelligence developed as a way of coping with large and complex social groups – may apply to whales and dolphins, as well as humans.
Writing in the journal, Nature Ecology and Evolution [DOI: 10.1038/s41559-017-0336-y] [DX], the researchers claim that complex social and cultural characteristics, such as hunting together, developing regional dialects and learning from observation, are linked to the expansion of the animals' brains – a process known as encephalisation.
The researchers gathered records of dolphins playing with humpback whales, helping fishermen with their catches, and even producing signature whistles for dolphins that are absent – suggesting the animals may even gossip. Another common behaviour was adult animals raising unrelated young. "There is the saying that 'it takes a village to raise a child' [and that] seems to be true for both whales and humans," said Michael Muthukrishna, an economic psychologist and co-author on the study at the London School of Economics.

The only problem is authoritarianism.
Without authoritarianism:
laws are simply contractual obligations to which each individual has voluntarily agreed.
religions are simply personal philosophies by which individuals choose to live their lives as meaningfully as possible.
money is simply a logistical technology that enables complex cooperation, placing ever more control over society's resources into the hands of those who prove to be good stewards, and removing ever more control over society's resources from the hands of those who prove to be bad stewards.
