Why the emu cant fly

They can walk, run, and even swim but can not fly. Like ostriches, kiwis, cassowaries, and rheas they spend their entire life breathing and exploring the ground, not the sky.

So, the weight and height make it impossible for them to fly. By puny we mean weak and small. Their weaker wings can not carry 50 to 55 kilograms and support flying. Unlike all flying birds out there, emus are blessed with a flat breastbone that lacks the kneel. The kneels are responsible for anchoring the pectoral muscles required for flying.

There is still a lot you need to know. As we are solely writing this article to enlighten our readers, it must contain all necessary information so that our readers can speak about it confidently as well.

Emus can simply do anything that other birds do. They can walk, run, and jump but unfortunately like all big birds out there, they can not fly at all.

If they had feelings or they could understand, they would probably get hurt as the human world can be sometimes cruel for birds and animals as well. Emus have been living on the ground since the beginning of time. They have never felt what flying feels like. All they do is walk, run, explore, and jump around. For a long time, we all kept believing that the size, puny wings, and kneel-less flat breastbone are all collectively responsible for the Emus inability to fly.

Everything was going fine but now a recent study took the world by storm, as per the research tweaks in DNA should be blamed for the Emus inability to fly. Puny wings are not just there without any purpose. If other birds use their wings for flying, Emus use them for a specific purpose as well.

The reality is quite different, there are several other big and small birds as well that have wings but can not fly. The other birds are;. Even though emus do not know the art of flying, they are not afraid of letting the wind blow through the feathers at all. They may not fly but they do spread their feathers quite often to feel the freedom. Amid little selective pressure to fly, these birds have lost the flying ability over time.

For penguins there was an immense pressure to be better swimmers, which provided a greater advantage in terms of food over flying, with the two abilities requiring a tradeoff. Probably nature cannot allow you to be both a great flier and a swimmer! Likewise, with the extinction of dinosaurs about 65 million years ago, many birds like ostrich and emu facing no challenge from predators made land their permanent base.

These birds preferred to nest and feed on the ground and therefore, had a natural disposition to be earth-bound. They gave up flying altogether just over a few generations. Their bones once hollow became dense, sturdy feathers turned to fluff, wings shrank and in some cases, disappeared entirely. Their keel-like protrusion on their sternums where the flight muscles attach, shrunk or disappeared, except in penguins who repurposed them for swimming.

Some birds like ostriches and emus ballooned in size, while others like kiwi remained small. But their legs became thicker, feet sturdier and coupled with strengthened and newly developed thigh muscles, these birds turned into formidable runners. The role of genetics, particularly regulatory DNA which can increase or decrease the function of specific genes in an organism is being extensively studied in rendering these birds flightless.

It is probably the mysterious regulatory DNA that triggered functional changes like strengthening of limbs, changes in wings etc. The highly shrunken wings of the flightless birds are vestigial, though used for other means. The birds can tuck their heads beneath their wings for warmth, or flash them at prospective mates or shelter eggs with them, or even use them to stir as they charge across the plains.
