In January 2009, we released a new Conservation (25) track for the human hg18 assembly that displays multiz (7) multiple sequence alignments of 43 vertebrate species to the human genome, plus two different measurements of evolutionary conservation. In addition to the assemblies included in the previous (28-species) Conservation track (9), we have added four new high-coverage (>6×) assemblies: orangutan, marmoset, zebra finch and lamprey; and 12 new lower-coverage assemblies: gorilla, tarsier, mouse lemur, kangaroo rat, squirrel, pika, alpaca, dolphin, microbat, megabat, rock hyrax and sloth.
