Researchers: Sponges definitely oldest animals, not “anatomically complex” comb jellies
| December 4, 2017 | Posted by News under Evolution, Intelligent Design, stasis |
This is a complex and long-running dispute. From ScienceDaily: Commenting on the breakthrough research, Professor Pisani said: “The fact is, hypotheses about whether sponges or comb jellies came first suggest entirely different evolutionary histories for key animal organ systems like the nervous and the digestive systems. Therefore, knowing the correct branching order at the root […]
Genetic Literacy Project objects to the term “living fossils” as applied to humans
