Can two different species co-exist? Humans can’t co-exist with each other. They look for features that make them different and this brings to conflict between them. However, animals showed people many times that they different species can co-exist and they should do it. There are different situations in life when mother has to feed orphan babies of some other aniimal and it often happens so that they agree and become a very good mothers for them. This lioness adopted a leopard cub in Ngorogoro Conservation Area in Tanzania. His mother was killed and this little baby would die without essential vitamins lioness could provide for him. He could become an easy prey but he became her baby. This is so touching!
