The Middle Cambrian chordate known as Pikaia gracilens was once thought to be humanity’s earliest known ancestor, and the earliest known member of the phylum Chordata.; Now, a new study flips ...

The origin of the body plan of our own phylum, Chordata, is one of the most fascinating questions in evolutionary biology. Yet, after more than a century of debate, the evolutionary origins of the ...

Phylum: Chordata (animals that have a notochord at some point in their lives; in fish, reptiles, birds and mammals, the notochord becomes the vertebral column) Class: Mammalia.

They belong to the phylum Echinodermata, which includes starfish and sea cucumbers, whereas humans belong to the phylum Chordata, or all animals with a notochord during some point in their ...

Scientists say that is an astounding discovery because it's an animal belonging to the Phylum Chordata, which are animals with a dorsal cord, which also includes humans.

Lancelets (‘amphioxus’) are the modern survivors of an ancient chordate lineage, with a fossil record dating back to the Cambrian period. Here we describe the structure and gene content of the ...

“Salps actually, this will sound a little odd, they’re our cousins. They are very simple members of the phylum chordata,” said Coastal Carolina University marine science professor Juliana ...
