Song units, each lasting about 15-20 s, can be produced as singular calls or combined into phrases that, when repeated, form bouts of song. This might be caused by genomic admixture that may have taken place among some rorquals. They do however have bristles similar to a comb. [253] One hypothesis is that as blue whale populations recover from whaling, this is increasing sexual selection pressure (i.e., lower frequency indicates larger body size),[252] although given the difficulties in measuring length from living whales, there is little evidence for changes in body size since whaling ended. [271] The Australian pygmy blue whale diverged during the Last Glacial Maximum.
