Living fossil refers to a species that has remained relatively unchanged for millions of years, making them fascinating creatures. However, there are several other synonyms used to describe these species. Some refer to these creatures as "prehistoric" due to their origins before recorded human history. Others may describe them as "ancient" since they've been around for an incredibly long time. Another synonym for living fossils is "evolutionarily stunted," referring to their lack of adaptation over time. Regardless of the terminology used to describe them, living fossils are an exciting reminder of the incredible diversity of life on Earth and the fascinating stories held within it.
