Which hominin was fully bipedal?
kadabba was capable of bipedalism based on a single toe bone, but more postcranial remains will be needed to support this suggestion. So what about the Ar. ramidus itself? Dubbed “Ardi,” the skeleton described is by far the best-preserved early hominin to date.
Can we make a species extinct?
De-extinction is a very expensive process. Bringing back one species can cost millions of dollars. The money for de-extinction would most likely come from current conservation efforts. These efforts could be weakened if funding is taken from conservation and put into de-extinction.
How did the extinction of the passenger pigeon affect the environment?
Because the passenger pigeon congregated in such huge numbers, it needed large forests for its existence. When the early settlers cleared the eastern forests for farmland, the birds were forced to shift their nesting and roosting sites to the forests that still remained.
Why did trilobites become extinct?
Research published by a Michigan State University paleontologist suggests that an inconsistent molting style, coupled with inefficient physiology, contributed to the demise of these prehistoric relatives of today’s crabs and lobsters nearly 250 million years ago.
How do you research dinosaurs?
To discover how organisms lived in the past, paleontologists look for clues preserved in ancient rocks—the fossilized bones, teeth, eggs, footprints, teeth marks, leaves, and even dung of ancient organisms. Fossilized jaws, teeth, and dung provide important clues about what non-avian dinosaurs ate.
