What explosion And if you are talking about the Big bang it happened about 13.7 billion years ago
The sudden increase in invertebrate fossil diversity
Olympics occur how many years
One trend that did not occur during invertebrate evolution is the development of true segmentation in all invertebrate lineages. While segmentation is a prominent feature in some groups, such as annelids and arthropods, many invertebrates, including cnidarians and mollusks, do not exhibit this characteristic. Instead, invertebrate evolution is marked by a diversity of body plans and organizational structures, with some lineages remaining unsegmented throughout their evolutionary history.
The explosion of life with a diverse array of invertebrates and plant phyla occurred during the Cambrian Period, which lasted from approximately 541 to 485 million years ago. This period is characterized by the "Cambrian Explosion," a significant event marked by a rapid increase in the diversity and complexity of life forms, particularly marine organisms. Many of the major groups of animals, including various invertebrate phyla, first appeared during this time.
Leap years occur every four years.
As least 11 but no more than 13 leap years occur in 50 years.
the years are 6
four
Every 4 years.
There are many more invertebrate than vertebrate animals.
