Why can certain animals regenerate limbs but humans cannot?

Throughout evolution, certain animals have developed the ability to regenerate their limbs. This is mainly do to their size, genetic makeup, and their place on the food chain. Animals that are predators yet get preyed on by bigger animals tend to have this ability. The reason why humans don't have this is because we on the top of the food chain and we have the mental prowess to develop medicine to keep us living longer.

Certain animals have evolved the remarkable ability to regenerate lost limbs due to their unique genetic makeup and biological processes. While humans possess some regenerative capabilities, such as wound healing, our ability to regenerate entire limbs is limited. This discrepancy can be attributed to differences in our genetic pathways and developmental processes compared to those of certain regenerating animals, such as amphibians like axolotls or certain species of invertebrates See More▼ like certain species of ants (https://theantvault.com/collections/ants-for-sale ). These animals have specialized cells called progenitor cells that can proliferate and differentiate into various cell types needed for limb regeneration. Additionally, they possess signaling pathways and genetic mechanisms that allow for precise control and coordination of tissue growth. Understanding these mechanisms could potentially unlock new avenues for regenerative medicine in humans.

They evolved this way. Humans have never really needed to regenerate limbs, therefore we didn't evolve to. However, with our ever growing technology, we have limb replacements. They aren't as well functioning as a regenerated limb, however we are getting closer by the minute.
