Fascinating. Identification of a developmental hourglass in brown seaweed (kelp) in mid embryogenesis, like plants & animals Suggests evolutionary acquisition of multicelluarity relies on ancient genes that become entrenched early in multicellular lineages www.nature.com/articles/s41...
A transcriptomic hourglass in brown algae - Nature
Similar to other eukaryotes, brown algae exhibit transcriptome conservation that is consistent with the molecular hourglass model during differentiation in embryonic development.
