From The Cambrian Explosion to the Great Dying - The Permian Mass Extinction
250The Permian Mass Extinction: From The Cambrian Explosion To The Great Dying:
543 million years ago, during a period known as the Ediacaran, our planet would have seemed incomprehensible and alien even to a hypothetical time traveler. Earth's oceans contained so little oxygen that modern fish would have died quickly. A sticky carpet of microbes covered the seafloor, and on this carpet a limited variety of organisms proliferated, sluggishly slithering blindly over the mud and grazing on the microbes. Animal life was simple because there were no predators and therefore no need to defend or flee. But an evolutionary storm would soon overturn this tranquil world. Within a few million years, in the Cambrian period, this simple ecosystem would have disappeared, giving way to a world dominated by extremely diversified organisms with ultramodern anatomical features...
Learn all about the Permian mass extinction, the greatest extinction event in Earth's history, in this video. From the Cambrian Explosion to the Great Dying, discover the causes and effects of this catastrophic event and its impact on the planet's biodiversity. Don't miss this fascinating look into a significant moment in history.
Today, the general idea of an "animal organism" responds to rather consolidated morphological characteristics, such as the presence of a mouth and possibly four, six, or eight legs; and even when considering extinct species, the thought still goes to forms that recall modern ones, albeit with more bizarre characters. In reality, as paleontologists well know, things are very different. If we were to go back in time, we would be confronted with unbelievably strange life forms, or practically at the limit of observability in terms of size. There was a distant time, more than half a billion years ago when life on Earth consisted only of single-celled bacteria, algae, and only a handful of multicellular organisms. All creatures were essentially marine... even though the oceans could appear to be completely empty.
