They might not be your standard household pet, but mice have been groomed over time to live alongside us in our humble abodes. At least this …
Researchers Say Eyes – Not Legs – Initially Prompted Water Creatures to Move Onto Land
What encouraged some water species to evolve into land-based creatures? This is what some scientists attempted to determine by analyzing the bodies of terrestrial vertebrates that existed about 385 million years ago. (MacIver, Schmitz, Mugan, Murphey, & Mobley, 2017) They found that their eyes – rather than their limbs – may have played a large …
Evolutionary Misfits: The Zebra Swallowtail and the Pawpaw Tree
The Zebra Swallowtail (Eurytides Marcellus) and the Common Pawpaw (Asimina triloba) are both evolutionary misfits. A cursory glance at both may fail to yield a connection but a closer look shows a complex relationship between the butterfly and the fruit tree that gives us insight into the evolutionary path of both. Let us first examine …
We Now Know What Dinosaurs May Have Really Looked Like

We may not end the discussion anytime soon, but a new study has revealed additional details to help us draw more accurate conclusions. In a report published in Nature Communications, researchers shared what they found when they used high-powered …
19 Dinosaur Skeletons Have Been Found – What Do They Tell Us About their Evolution?
Dinosaur discoveries always give us more to consider when we look back on the evolution of today’s animals. The recent unearthing of 19 skeletons in the Gobi Desert of China is no different. On Dec. 22, scientists published new findings in Current Biology, detailing 19 skeletons they found while searching in the Gobi Desert. The …
Could Fish Fins be Linked to Human Hands? Maybe, Researchers Say
Could your fingers be linked to fish fins? Scientists’ new research may just lead us to the answer. A new study published by a team of researchers at the University of Chicago claim that there are significant evolutionary connections between our appendages and fish fins. Evolutionary biologist Neil H. Shubin has been seeking connections between …
Could a Diet of Nuts and Seeds Killed the Dinosaurs?
Many people naturally assume that a large catastrophic event, like an asteroid collision, caused the demise of the dinosaurs. However, a new study published in Current Biology by a group of Canadian researchers indicates that their diets and a changing environment might have also contributed to their downfall. Specifically, the research points to the teeth of fossils. …
