What other hominids evolved from the same common ancestor as humans?

Some of the most commonly known hominids that shared a common ancestor are:

Chimpanzees, Gorillas, Bonobo, Orangutan, and Neanderthals.

I hope this helped!

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
