Invertebrates are a diverse group of animals that lack a backbone and are classified into several phyla, including arthropods, mollusks, annelids, and cnidarians. They are related through their evolutionary history, sharing common ancestors, and they exhibit a wide range of adaptations to various environments. Invertebrates play crucial roles in ecosystems, contributing to processes like pollination, decomposition, and serving as food sources for other organisms. Their relationships can be studied through comparative anatomy, genetics, and evolutionary Biology.
