All of animal phyla on Earth today evolved during what period?
All animal phyla on Earth today evolved during the Cambrian Explosion, which occurred around 541 million years ago. This period marked a rapid diversification of multicellular organisms and the emergence of most major animal groups that exist today.
Which era did the most animal phyla evolve?
The Cambrian era saw the rapid evolution and diversification of many animal phyla, known as the Cambrian Explosion. This era, approximately 541 to 485 million years ago, was a pivotal time in the evolution of life on Earth, leading to the emergence of a wide variety of body plans and organisms.
How many total phyla?
There are around 35 recognized animal phyla and 11 recognized plant phyla, making a total of approximately 46 phyla across the animal and plant kingdoms.
Which characteristics are NOT present in all animal phyla?
Not all animal phyla possess a backbone or true tissues. Additionally, not all animal phyla exhibit bilateral symmetry or segmentation. Some phyla, like sponges, lack specialized organ systems, while others, like cnidarians, have a simple nerve net instead of a centralized nervous system.
How many phylum did we have?

Which structure is not an innovation that occurred during vertebrate diversification?
Exoskeleton
What was the significance of the Cambrian explosion to the evolution of life on Earth?
The Cambrian explosion was a period of rapid diversification of life forms around 541 million years ago. It marked the appearance of most major animal phyla, resulting in the development of complex multicellular organisms. This event set the stage for the subsequent evolution and diversification of life on Earth.
