CNN —The heads of most animals are easily identifiable, but scientists haven’t been able to say the same for sea stars until now. But new genetic research suggests the opposite — that sea stars are largely heads that lack torsos or tails and likely lost those features evolutionarily over time. There, they go through a process that transforms a bilateral body into a star shape, or pentaradial body. But echinoderms also share a common ancestor with bilateral animals, which adds to the puzzle researchers are trying to solve. Specific molecular markers act like body plan blueprints, directing each cell to the body region where it belongs.

Lucy's fossil includes 40% of her skeleton, one of the most complete Australopith fossils found to date. Edwin Remsberg/Alamy Stock PhotoAnalysis of Lucy’s fossil over the past 20 years has suggested that she and others of her species walked upright. Then, she used scans of Lucy’s fossil to determine how her joints were articulated and moved in life. Muscle modeling of Lucy, dubbed "AL 288-1," is compared side by side with human muscle maps. “Lucy likely walked and moved in a way that we do not see in any living species today,” Wiseman said.
