Big Spider, Big Genome: Chromosome-Level Genome of a North American Tarantula (Aphonopelma marxi) and Comparative Genomics Across 300 Million Years of Spider Evolution.

Within the Araneoidea lineage sampled in our analysis (Araneidae, Nephilidae, Linyphiidae, Tetragnathidae, Theridiidae), there was a clear trend of decreases in genome size and repeat content, supported by the strong positive correlation observed across the available genomes (Pearson's r = 0.74, P = 1.2 × 10 −4 ).
