Humans are notoriously different frombirds. They belong to another evolutionary branch, and as such, they have very little in common with creatures like us. However, it is worth speculating on what would have happened if birds had evolved as the dominant species instead of humans—with the resu...
To approach a question 400 million years in the making, researchers turned to mudskippers, blinking fish that live partially out of water.
When we hold our breath underwater, our spleens contract and release any extra red blood cells back into the circulatory system. Essentially, by having a larger spleen, the Bajau can increase how much oxygen they can carry or hold in a single breath. Did The Bajau Just Get Lucky? Why Do...
Which of the following statements about respiratory and circulatory systems is not true? A. Amphibians can shut off their lungs when underwater, with blood flow continuing only to the skin, thus allowing skin breathing. B. ...
Describe the evolution of major animal phyla (name 8 of them) and explain how they are related to each other by describing which phyla they share and which they do not share 7 major characteristics. Explain how the world would be different if C4 plants and CA...
"It's interesting that many people who like shrimp and lobster think insects are yucky," she said. "But shellfish are kind of like underwaterinsects."
discovered a way for humans to potentially breathe underwaterby merging our DNA with that of algae. ... The real-life version however could work on a more fundamental level and change our DNA so that we are more like algae, which actually give off oxygen even though they are on the sea...
They spent less time chewing, so they could spend more time making tools. They could burn down entire forests, if they so chose, to provide a better environment for the desired types of wild plants to grow. They could use the heat from fire to move to colder environments than the one ...
After identifying the most promising bacteria, the scientists had a new question: among all the chemical compounds produced byP. cichorii, which one was keeping the fungi at bay? To find out, they used mass spectrometry and molecular networking techniques. They also observed the interactions betwee...
Fast-accumulating data seem to indicate that our close cousins, the Neanderthals, were much more similar to us than imagined even a decade ago. But did they have anything like modern speech and language? And if so, what are the implications for understan
