Answer:
The messenger pigeon is a variety of domestic pigeon (Columba livia domestica) derived from the rock pigeon, selectively bred for its ability to find its way home over extremely long distances. The wild rock pigeon has an innate homing ability,[1] meaning that it will generally return to its nest, (it is believed) using magnetoreception.[2] This made it relatively easy to breed from the birds that repeatedly found their way home over long distances. Flights as long as 1,800 km (1,100 miles) have been recorded by birds in competitive pigeon racing.[3] Their average flying speed over moderate 965 km (600 miles) distances is around 97 km/h (60 miles per hour)[4] and speeds of up to 160 km/h (100 miles per hour) have been observed in top racers for short[clarification needed] distances.

The mitochondria is the powerhouse of the cell, without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration.
