How do homologous structures provide evidence
WebView Evidence for Evolution Webquest.docx from ACC 123 at South View High. Evidence for Evolution Webquest Overview: You will explore the following pieces of evidence: 1. Homologous WebHomologous Structures Homologous structures are structures, or body features, that are similar in two different species. The structures are similar because they were inherited from a common ancestor. Scientists can examine homologous structures to determine how closely related two species are to each other on the phylogenetic tree of life.
