100 POINTSThe picture below shows the bone structures of human, cow, and horse. Picture shows similar bone structures of human, cow, and horse.

Based on the diagram, which of these statements is correct about humans, cows, and horses?

They have developed from the same organism.
They have completed their evolutionary process.
Humans have evolved from several ancestors.
Horses have evolved from cows and humans.

option A they have developed from the same organism

Explanation:

Organs of animals (belonging to different species) which have similar structure but different functions are homologous organs. Such organs have evolved from the same ancestors , however their function are different.  

For example – wings of bats, limb of human etc.  

Here in this case  also the bone structures of human, cow, and horse are same but their functions are different, thus they are homologous organs and hence they have evolved from same ancestors.  

The correct answer is option A

"They have developed from the same organism."

there really is life in the deepest part

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.
