Their tiny wings probably can't lift their heavy body off the ground. May 13, 2014 Ostriches also have feathers in their ancestors, and because they were flying birds, they have feathers. Therefore, ostrich feathers are the result of biological inheritance. However, over time, these birds have lost the ability to fly due to evolution. They gained weight and couldn't fly and adapted to the land. The ostrich's ancestors were actually flying birds, but lost their ability to fly due to the conditions mentioned above. Ostriches have not only evolved in such a way that they lose their ability to fly. They actually forgot how to fly. This loss of knowledge can contribute to evolution. Newly studied fossils suggest that ostrich ancestors are instead within the "Risonis-Cohort," a group of North American and European birds that had the potential to fly. Kiwis may have occurred separately. In fact, the reason it doesn't have a tail is that it boycotted this feature when hardcore religions were announced. By the time Obsidian got rid of it, it was too late because they had already rendered Nishka.

Ostriches are so large that they cannot actually fly. There are other big birds that can still fly. I can't fly because I don't have a sternum

How did the ostrich lose its ability to fly?
The ostrich's ancestors were actually flying birds, but lost their ability to fly due to the conditions mentioned above. Ostriches have not only evolved in such a way that they lose their ability to fly. They actually forgot how to fly. This loss of knowledge can contribute to one thing: evolution.
What are the ostrich ancestors?
The ostrich's ancestors were flying birds. DNA evidence proves the fact that these birds flew to different continents and lived in different places. Ostriches evolved about 60 to 65 million years ago when they were once flying. They later gained weight and became flightless birds.
Why does an ostrich have no tail?
This is the same reason that humans have a coccyx but not a coccyx. The tails are useless to human species, but our ancestors (primates) had them. Ostriches actually have wings, but they are used differently. Animals are known for their fast speed.
How did the ostrich evolve so that it wouldn't fly?
One of these birds was an ostrich. Over time, as evolution began, ostriches grew in size and began to adapt to their "new" life. And as these birds grew larger, they began to lose their ability to fly. 16окт. 2011
Why can't penguins and ostriches fly?
In fact, penguins are the only birds that can't fold their wings. The bones of their wings fuse straight together, making them stiff and strong like flippers. Similarly, penguins are little worried, as light as a flying bird.
Why can't chickens and ostriches fly?
The main reason ostriches can't fly is actually related to the feathers themselves. The individual globules are not interlocked like the wings of a flying bird. This means that the wings do not provide wind resistance to get out of the ground. These are the two main reasons ostriches can't fly. The 23rd.2016
Did the ostrich fly?
Flightless birds can't fly I'm glad that ostriches and emu from ancestors don't fly. However, DNA evidence suggests that their little ancestors flew to each continent, where they evolved independently into giants with chunky wings.
