- is made of cells derived from several different lineages. One might have expected that the earliest cell divisions would produce daughter cells destined to go on to form a single structure in the embryo. But that is not generally the case.

Different angiosperm evolutionary lineages differ in the distribution between nucleus and mitochondrion of genes for the proteins of mitochondrial ribosomes, suggesting multiple events of transfer of genes from mitochondria to nuclei (ref).

Shared derived characters that are regarded as homologous are called synapomorphies, e.g. the presence of mammary glands in all three lineages of mammals (monotremes, marsupials and placentals).
