Certain insect colonies typically make good "individual" analogues due to certain roles being infertile and so the genetic lineage actually working in units that are larger than a single bee.
If you think about it, the way we define an individual is a bit blurry anyway - think of those plants and creatures which produce more "individuals" by letting pieces break off and float down the river to take root elsewhere, or reproduce asexually to produce clones. Aphids, for example, on the same plant are commonly clones.
So you can cling tight to the individual as being the thing that is delineated by a mixing of genes in sexual reproduction and have things still make some sense. But if you let that slide and zoom out then indeed life as we know it is just one branching, breaking, mutating organism.
