Emerging viruses have been the cause of several epidemics in recent decades: Spanish flu, Hong Kong flu, Chikungunya, Dengue, Ebola, SARS-CoV, MERS-CoV, and SARS-CoV-2 have all caused serious human and social damage across the world.
The vast majority of these emerging viruses come from animals: first of all, they predominantly infect one animal species (ape for the Ebola virus, poultry in the case of the H5N1 avian influenza virus, etc.). Then, what can happen is that via various genetic mechanisms (mutations, rearrangements, etc.), they manage to adapt to humans, i.e. they manage to efficiently enter our cells, multiply there and then spread between people.
