When did life start on Earth and how do they know? Life on Earth is believed to have originated around 3.5 billion years ago, as evidenced by the discovery of microfossils and biomarkers in some of the oldest rocks on the planet. These rocks, found in places like Western Australia, provide...
Unfortunately, we don't have time machines to take us back to the time of the pterosaurs, but we do have paleontologists, scientists who study and interpret fossils. They've been able to use old rocks and bones to discover some pretty amazing things about how these creatures evolved, what...
For 130 years, we thought we understood the broad architecture of the dinosaur family tree. British palaeontologist Harry Seeley pointed out in 1887 that dinosaurs could be divided into two groups based on whether their hips were lizard-like (where the pubis points forward) or bird-...
According to the Flood narrative, in the past 4,350 years, 7 billion of us descended from Noah and his wife Gertrude (or whatever). “But you have English ancestry, don’t you?” she asked me. “No, I do not,” I said. Somehow race and English ancestry are tangled up in this Cr...

For example, we tend to think of bird feathers as beautiful adaptations for flight because they do such a great job of enabling flight today, but the evolutionary history of feathers tells a different story. Recently, paleontologists have unearthed many fossils of feathered, but flightless, ...

When NASA’s Perseverance rover launches this summer, it will face one of the most ambitious missions in any space exploration project to date: To search forevidence of life on Mars. If there ever was life on Mars, there almost certainly isn’t now — so...
Prehistory:Prehistorical times refers to any time period before the dawn of writing 5,500 years ago. Much of human evolution took place in prehistorical times. To know about this time period, we need to use information gained from archaeological artefacts.Answer and Explanation: ...
Explain how excavating sediments reveals an ordered series of fossils. What makes isotopes of an element different from one another? How do we use isotopes to date objects? Describe the importance of Carbon to life on earth. Include details regarding (a) chemical properties and b...
