Is it even possible, for example, for a bird to not know how to build a nest, or for a beaver to not know how to build a dam?
In: Biology
The drive you are referring to, is called instinct. “DNA plays a critical role in these processes, but does not by itself create traits. Accordingly, instincts are not preprogrammed, hardwired, or genetically determined; rather, they emerge each generation **through a complex cascade of physical and biological influences**”
What they mean is they’re not born knowing these things, but instead they reliably develop as habits or practices due to the creature’s development and environmental circumstances.
The result of this being there ARE occasionally animals that fail to develop a common instinct for their breed, but also animals that develop their instincts even in compromised environments. For example, there is an orphan beaver that lives in a house with people, yet is still compelled and pushes it’s toys to one place to dam them up.
