The three main groups within Phylum Chordata are: Cephalochordata (lancelets), Urochordata (tunicates), and Vertebrata.

The amniotic egg provides a protective barrier from the environment, shielding the developing embryo.

The amniotic egg's shell prevents water loss, allowing animals to thrive in drier environments.

Vertebrae provide a strong internal framework for support and enable efficient movement.

The cranium (skull) provides protection for the brain, a vital organ.

Fur acts as a layer of insulation, keeping animals warm in cold environments.

Milk provides essential nutrients to young offspring, supporting their rapid growth.

Jaws enable animals to catch and consume prey efficiently, giving them a significant advantage.

Limbs allow for movement on land or water, while lobed-limbs are an evolutionary intermediate form between fins and limbs.

Limbs facilitate efficient movement on land, opening up new habitats and opportunities.

Key derived characteristics that define the phylum Chordata, including a notochord, dorsal hollow nerve cord, pharyngeal slits, post-anal tail, and endostyle.

The notochord provides structural support and flexibility, allowing for efficient movement and locomotion.

A mammal belonging to the order Primates, characterized by five-fingered hands, five-toed feet, and large brains.

A member of the hominid family, specifically including humans and their extinct ancestors.

A widely accepted hypothesis explaining human evolution and migration, suggesting that modern humans originated in Africa and subsequently migrated to other parts of the world.

Lungs are responsible for gas exchange, taking in oxygen and releasing carbon dioxide.

Lungs allow for a greater surface area for gas exchange, providing a more efficient way to obtain oxygen compared to diffusion through skin.

Lungs evolved from a swim bladder, an organ in fish that helps them control buoyancy.

Scales provide protection from predators and infections, and help to reduce water loss.

Scales are flexible and lightweight, allowing for efficient movement in water.

Lancelets are small, fish-shaped marine animals that lack distinct heads and specialized sense organs.

Tunicates are marine animals that are filter feeders and have a sac-like body covered in a tunic.

Hagfish and Lampreys lack jaws, but have cartilaginous skeletons.

Vertebrates that typically live in water during their larval stage and on land as adults, characterized by smooth, moist skin and lacking scales or feathers.

A group of vertebrates that have a fertilized egg covered by a membrane, which allows them to reproduce on land.

Amphibians are characterized by a smooth, moist skin and lacking scales or feathers. They typically transition from an aquatic larval stage to a terrestrial adult stage.

A group of mammals that lay eggs, possess a pouch, and have mammary glands.

Mammals that give birth to relatively undeveloped young that finish development within a pouch on the mother.

Mammals that possess a placenta, which allows for the exchange of nutrients and waste between the mother and developing embryo.

The placenta serves as a lifeline, facilitating the exchange of nutrients and waste between the mother and developing embryo. It allows for the transfer of oxygen and nutrients to the growing embryo and removes waste products.

A group of primates, including modern humans, that are characterized by bipedalism, larger brains, and complex social structures.

Primates possess five-fingered hands, five-toed feet, large relative brain size, and complex social behavior.
