Another change for you is the birthing process for humans is much harder than that of any other animal.
A human female is completely helpless for a much longer time during birth than any other animal - this requires a strong social structure to defend her.
Another change is the enormous amount of time it takes a human to mature. Again, this requires a complex social structure to provide for children for a long time.
I guess you're not familiar with the Kiwi bird, then. I think they qualify as the longest birthing process, with their eggs weighing about 1/4 the weight of the entire bird, and where laying an egg incapacitates the female for months. Of course, as with many birds, kiwis have a strong social structure, mating for life, and with the male participating the birthing process through incubating.
It's almost as if some animals have strong and complex social structures, too. Humans are indeed like other animals.
According to wikipedia it takes 1 month, not months, and the bird is only incapacitated toward the end of it.
The children of a kiwi bird are not fed by the parent in some of the species, and they leave the nest within a few days to a month, despite the bird living possibly 30 years.
No social relationships with other kiwis is required - only with the mate.
So your example falls totally flat.
Obviously some animals have one or another trait that compares to a human, but none have all of them - none even come close. Humans are not anything like other animals.
Not sure what pattern you want me to see - you need more than one example to make a pattern.
A human female is completely helpless for a much longer time during birth than any other animal - this requires a strong social structure to defend her.
Another change is the enormous amount of time it takes a human to mature. Again, this requires a complex social structure to provide for children for a long time.
Can you sense a pattern here?
