Hola a todos Why did God create bugs, some animals and fish ๐ฆ ๐ชฒ to have the ability to regenerate limbs, and even organs, while humans ๐ฆ๐ผ and mammals๐ฐ cannot? I did some searching, and insects like spiders, young grasshoppers, and stick insects can regenerate body parts. If, for example, a spider loses its leg, it can grow the leg back again. Some things like worms even can regenerate heads. if they regenerate their heads, will they still have any memory? And zebrafish can even regenerate hearts and spinal cords. So why canโt humans and mammals regenerate limbs? Gracias ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ๐ธ
