The evolution of symmetry, tissues, a body cavity, patterns of embryonic development, and segmentation (repeated body units).
Symmetry is found as radial symmetry (halves of the body mirror each other) and bilateral symmetry (symmetric in every direction).
Cells differentiate into tissues which allows for specialized structures and functions.
The evolution of body cavities allowed for the evolution of organ systems.
There are 2 patterns of embryonic development in bilateraly symmetrical animals: protostomes and deuterostomes. Other embryonic development classifications are cleavage patterns (spiral and radial), determinate or indeterminate development, and coelom formation.
With segmented animals, each segment has a set of organ systems. This is advantageous because if one segment is damaged, the animal will not die. Segmentation also allows animals to move more effectively since the segments can move fairly independently.

How many criteria are used to classify organisms into kingdoms?
Organisms are classified into kingdoms based on five main criteria: cell type (prokaryotic or eukaryotic), cell structure, mode of nutrition, body organization, and reproduction methods. These criteria help scientists categorize organisms into distinct groups to better understand their relationships and evolutionary history.
What are five evolutionary forces?
The five evolutionary forces are natural selection, mutation, genetic drift, gene flow, and non-random mating. These forces can lead to changes in allele frequencies in a population over time, resulting in evolution.

Organisms are grouped into a five-kingdom classification system based on their structure and?
Organisms are grouped into a five-kingdom classification system based on their structure and characteristics such as cell type (prokaryotic or eukaryotic), mode of nutrition (autotrophic or heterotrophic), and body organization. The five kingdoms are Monera, Protista, Fungi, Plantae, and Animalia. Each kingdom represents a different group of organisms with unique traits and evolutionary relationships.
