The picture shows the members of the Camelidae family. The physical features and the geographical origin of these animals provide evidence that - 

• they live in the same type of environment.
• have slowly evolved to become herbivores.
• have a common ancestor.
• exchanged DNA in the past.

• exactly the same DNA sequences
• no proteins in common
• completely different DNA sequence

• Have very similar skeletal structures
• belong to the same species
• must range great distances to eat
