HERVs are classified based on their homologies to animal retroviruses. These analyses also revealed many possible homologies with Proteobacteria. The noncoding region has a homologies with BPV1. Our goal is to compare the iterated homologies formula 121 and formula 122. To both Darwin and Owen such "homologies" in comparative anatomy were evidence of descent. There are several equivalent Floer homologies associated to closed three-manifolds. Among the many homologies in mammal reproductive systems, ovaries and testicles are homologous. This would allow for these sequences to be compared to try to find homologies. The homologies of the various basal sclerites are open to debate. Floer homologies are generally difficult to compute explicitly. With more elements the higher-dimensional Koszul homologies measure the higher-level versions of this. The homologies between these have been discovered by comparing genes in evolutionary developmental biology. Several homologies encourage this view, such as correlating segments of the appendages and the prosoma. There are also homologies between the sub-tropical climates of areas of the two countries.
