How Did Birds Get Their Wings? Bacteria May Provide a Clue, Say ScientistsNew research has used bacteria to show that acquiring duplicate copies of genes can provide a 'template' allowing organisms to evolve novel traits from redundant copies of existing genes.University of Oxford...
Where did insect evolve from? It is estimated that the class of insects originated on Earth about 480 million years ago, in the Ordovician, at about the same time terrestrial plants appeared. Insects may have evolved froma group of crustaceans. ...
Did birds evolve from theropods? How are marsupials different from eutherians? How did dinosaurs evolve feathers? How are marsupials and monotremes similar? How diverse are marsupials? How are sharks different from bony fish? How are sauropods and theropods related?
Wing-Assisted Incline Running (WAIR): Modern birds, such as young partridges, use their wings to help them run up steep inclines. This behavior supports the idea that feathered dinosaurs might have used their proto-wings in a similar way, gradually developing the ability to glide and eventually...
Think of a modern bird. When you eat chicken wings, you won’t find claws, but dinosaurs had them. This is known as mosaic evolution, where different parts of the body evolve at different rates — like assembling a biological jigsaw puzzle. It highlights the complexity of early bird evoluti...
How did the largest of all dinosaurs evolve necks longer than any other creature that has ever lived? One secret: mostly hollow neck bones, researchers say. The largest creatures to ever walk the Earth were the long-necked, long-tailed dinosaurs known as the sauropods. These vegetarians had ...
How did birds evolve? If all animals evolved from some kind of fish millions of years ago and that fish eventually made it onto land through several mutations, I don't understand how birds could possibly evolve from this. Maybe this land creature's offspr How does the process of direc...
Learn how animals communicate through sound! Explore the fascinating world of animal communication and discover the secrets behind their unique vocalizations and signals.
Just as wings open up this sphere of air for birds to exploit, language opened up the sphere of cooperation for humans to exploit. And we take this utterly for granted, because we're a species that is so at home with language, 00:00 but you have to realize that even the ...
The formation of UV patterns is based on small structures in the scales on butterflies’ wings. Although these structures are on a microscopic scale, they could be closely related to large-scale phenomena, such as the distribution of populations with different levels of UV reflectance. For this ...
