No, never. The type of species is simply the covering known as the body. Within each of these bodies (whether it is a dog, ape, human or even a worm), the jivatma alongside the Supreme Lord Sri Hari (as the supersoul resides). That is why no-one is lower or higher, every living being is worthy of respect. That is why Sri Krsna says in Gita, "Pandit sama darsinah" (the wise see these entities as equal). This principle of Ahimsa is central to all nearly all schools of Hinduism including us. That being said, Human birth is unique because only humans have the sufficient consciousness development to utilize the power of "vivek" (discrimination). Only humans can discriminate between the permanent (God) and the impermanent (Maya) that is why only they are fit to attain Moksha. This is confirmed in Sripad Sankaracharya's Vivekachudamani (verse 3):
"
durlabha trayamevaitad
devanugrahahetukam
manusyatvam mumuksutvam
mahapurusamsarayah"
"Very rare indeed are these three things and happen only due to the utmost Grace of God—a human birth, a burning desire for liberation, and the blessed refuge of an Mahapurusha (a realized saint)"
That is why Human Birth is praised in Sruti and Smrti. However that being said, no being deserves to be exploited by humans. Everything is for the pleasure of the Supreme Lord, and He is the only enjoyer and we are the enjoyed. This is confirmed in Isopanisad:
"Om Isavasyamidam sarvam yatkiñca jagatyam jagat
tena tyaktena bhuñjitha ma grdhah kasyasvid dhanam"
"Everything moving or non-moving is owned and pervaded by Ishwara (Sri Krsna). Therefore you should accept only what is given to you (to maintain your life) and refrain from seeking the wealth of others (i.e exploitation of others)"
That being said Lord Gauranga Mahaprabhu was so merciful He gave Krsna Prema (love of God) to even the lions, tigers and elephants in the jungles of Jarkhand by inspiring them to do Harinama Sankirtan.
@kalyan ji I can understand why you are so passionate for this topic, but I humbly request you to tone down the insults. Everyone believes what they to according to the level of faith that the Lord awakens in their heart. Even in our perceptive they may be wrong, that faith is still strengthened and provided by Sri Hari therefore we should respect that, and engage in debate respectfully so we can understand the position of others. If we cannot convince others with philosophy, let us try to do so with exemplary Vaishnav behavior. My Gurudeva once said to us, "when you go to take the association of another group who have different views to you, do not correct them, argue with them, or try to push your view upon them. Take the positive aspects of their wisdom and teachings and disregard the negative, just like a swam extracts the milk from water". Perhaps I have not followed this order as well as I could and hence I ask for forgiveness at his feet.
Let us come together in a mood of understanding rather than criticism which seeks to divide. I apologize to everyone in this thread for any offense I or (Kalyanji) may have caused
We are simply trying to clarify our position according to what our Gurudeva and Purva Acharyas have taught us.
