ELI5: Why do primitive animals/species know how to animal/specie by themselves, while us humans have to be taught since birth almost everything?

For example, some animals are hatched/born alone (without their father/mother anymore), and venture out alone until adulthood, without any help from others of their species. Whereas us humans have to almost be spoon-fed stuff in out early stages of life. Just a thought, no shaming/nonsense answers please.

Actually, humans are born with the innate knowledge and ability to survive as is necessary for a baby. We're born with a suckling instinct, for example, to latch onto nipples and draw food. We also have all the autonomic reflexes already, such as ticklishness, breathing, heart rate regulation, etc. These are common to all mammals, of which we are a member.

This is because primates are social animals; we are born into a group collective (a family unit) and predictably have a social group to learn from. You have to remember that when it comes to survival, humans know everything they need to know right when they're born, because all that is required of them is autonomic in nature (breathing, heart rate, feeding, urinating, defecating, sleeping, waking), and we only require more complicated systems when we've grown.
Humans as a whole are very weak when they're first born, and require a great deal of security for quite a long time, compared to other animals. This is likely because we devote such a great percentage of the nutrients we ingest in order to develop our brains, as opposed to most other animals needing only to develop their bodies. This is likely why parents have an overwhelming emotional bond with their children.

Some animals are not social, and are therefore unable to learn from others of their species, and so they're born with (or learn shortly after birth) more complex instincts.
