A living fossil is a term used to describe species that are still alive today but have body structures and appearances that have changed very little compared to their ancient ancestors found in fossils.

When studying living fossils, scientists have found that the rate of evolution in these organisms is usually very slow. Over millions of years, their biological traits, body structures, and lifestyles have remained largely unchanged. Because of this, they provide valuable information for scientists to better understand the evolutionary history of life on Earth.<\/span><\/p>\n

Let\u2019s explore some living fossil species, much like flipping through the ancient diary pages of our Earth. These organisms have witnessed the formation and breakup of supercontinents, as well as the rise and extinction of the dinosaur empire, yet they themselves have endured through time. Below are a few notable examples often mentioned when discussing living fossils.<\/span><\/p>\n

The coelacanth is one of the most famous examples when discussing living fossils. This fish originated in the Devonian period, around 400 million years ago, and for a long time scientists believed it had gone extinct at the same time as the dinosaurs\u2014until a living specimen was discovered in 1938.<\/span><\/p>\n

The ginkgo tree is the only surviving species of an ancient group of plants that flourished about 270 million years ago. While all of its relatives have completely disappeared, the ginkgo has endured through ice ages and dramatic climate changes. Its remarkable survival is largely due to its strong resistance to diseases and its ability to repel insects effectively.<\/span><\/p>\n

In another corner of the Earth, the platypus (Platypus) is believed to have existed for about 167 million years. According to experts, it is one of the very few egg-laying mammals that still exist on Earth today.<\/span><\/p>\n

The platypus has a rather unusual and almost comical appearance, featuring a duck-like bill, a beaver-like tail, and otter-like feet. It is also one of the rare venomous mammals. Male platypuses have a spur on their hind legs that contains venom capable of causing intense pain to other animals.<\/span><\/p>\n

However, unlike many venomous insects or reptiles, the platypus mainly uses its venom during the breeding season to compete with rivals, rather than to kill or weaken its prey.<\/span><\/p>\n
