Basically this is the equation...
animal propensities + dharma (selfless service to God) = human being
human being - dharma (selfless service to God) = animal propensities
Today, essentially human civilization is glorified animal civilization (as God is not the center). Not surprised with all the fighting going on between nations, communities and people!
Below is the verse.
sāmānyam etat paśubhir narāṇām
dharmo hi teṣām adhiko viśeṣo
dharmeṇa hīnāḥ paśubhiḥ samānāḥ
Eating, sleeping, sex, and defense—these four principles are common to both human beings and animals. The distinction between human life and animal life is that a man can search after God but an animal cannot. That is the difference. Therefore a man without that urge for searching after God is no better than an animal.
