REGENERATION

Regeneration of libs in salamanders is given by epimorfosis, sells are able to reconstruct the entire limb if necessary but can also reconstruct only the missing parts. After the amputation between 6 and 12 hours endoderman cells lining the wound, this layer called the epidermis proliferates forming a wound a pical ectodermal cap. During the following days the cells are under the cover dedifferentiate into a mass,tghe regeneration blastema. Genes expressed in differentiated tissues are negatively regulated the expression of genes associated with embryonic limb undergoes a dramatic increase. These cells continue to spread and eventually metamorphose to form the new structures of the limb.

1. If asexual reproduction (cloning) is natural why is it negative?

I dont now why is negative, I think that is positibe because there are goin to be more animals.

2. what would happen if humans could clones?

They`ll be without identification, the resources will be depleted,the economic resources will be depleted.
