👤 whose
Whose fossil work first highlighted the mammal-like reptile ancestors of modern mammals?
Quick Answer
Richard Owen and later paleontologists described many fossils of synapsids and therapsids. These animals are key ancestors in the mammal lineage.
The Full Story
Nineteenth-century paleontologists, including Richard Owen, helped recognize a group of fossils now known as synapsids, later including therapsids, which are on the evolutionary line leading to mammals. These ancient animals had a mixture of reptile-like and mammal-like features. Their study helped scientists understand that mammals did not appear suddenly but evolved gradually from earlier vertebrates. This fossil evidence is central to the story of mammal evolution.
Key Facts
1.Synapsids are the lineage leading to mammals
2.Richard Owen was a major 19th-century comparative anatomist
