Genomic DNA from one living male Octopus bimaculoides and 12 RNA transcriptomes from tissue and developmental samples document gene-family expansion and genome rearrangement; the methods support present-day sampling, not species origin.

event-mechanism · highThe Octopus bimaculoides assembly and 12 RNA transcriptomes document expanded protocadherin and C2H2 zinc-finger families, extensive rearrangement and tissue-specific expression patterns. The study found no evidence for proposed whole-genome duplication, but did not rule out duplication followed by extensive gene loss.
claim:event:octopus-genome-innovationevent-mechanism · highThe Octopus bimaculoides genome and 12 RNA transcriptomes document gene-family expansions and rearrangement. The study found no evidence for whole-genome duplication but did not exclude duplication followed by extensive gene loss; these samples do not date octopus origins.
claim:taxon:octopus-bimaculoidesfossil-range · highAlbertin et al. sequenced genomic DNA from one living male Octopus bimaculoides and used 12 RNA transcriptomes from tissue and developmental samples to annotate the assembly. These are present-day research samples, not dates for species origin, fossil first appearance or complete geographic range.
