According to reason, all organisms on Earth, including humans, evolved from the cyanobacteria on Earth. All accidental incidents that occurred billions of years ago on Earth have become the foundation for all existing organisms.
The reason why most organisms rise early and rest late is because the early bacteria's release of oxygen followed a pattern with diurnal rhythms.
The reason why most organisms engage in mating and reproduction is because the birth and evolution of early single-celled organisms and later advanced organisms fundamentally aimed to protect genetic information.
To protect genetic information, organisms evolved various abilities for resource competition or self-preservation.
The salamander's regeneration ability, the venom gland ability of venomous snakes, and the most common sharp claws and teeth among carnivores.
All these are actually to protect genetic genes.
Protect oneself, protect offspring, protect the entire group.
