Most phylogenies therefore are hypotheses and are based on indirect evidence. Different phylogenies often emerge using the same evidence. Nevertheless, there is universal agreement that the tree of life is the result of organic descent from …

Concept 25.1 Phylogenies are based on common ancestries inferred from fossil, morphological, and molecular evidence Sedimentary rocks are the richest source of fossils. Fossils are the preserved remnants or impressions left by organisms that lived in the past. In essence, they are the historical documents of biology.

a phylogenetic study of alphaviruses, derived from a bayesian analysis of whole-genome sequences, is in essential agreement with their serologic classification, although the resolution is slightly different. 17 all the medically most important alphaviruses group into two clades: the semliki forest clade, including chikv, o'nyong-nyong virus, and …

DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are. Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change. Fossils.
Trace Evidence: Introduction
http://www.forensicsciencesimplified.org/trace/
Trace evidence can include a wide variety of materials, but the most commonly tested are hair, fibers, paint and glass. Other, less frequently included items are soil, cosmetics and fire debris. Some laboratories will consider fire accelerants as trace and others will include them in chemistry, even though the same tests are conducted in both laboratories.
Pre-lab Homework Lab 9: Tracing Phylogeny
https://spot.pcc.edu/~wdubbs/bi102/Lab%2009%20-%20Phylogeny.pdf
Homologies in morphology, anatomy, embryology and DNA sequences can all be used to build a phylogenetic tree. However some species resemble each other because they independently evolved similar structures in response to similar environments or ways of life, not because they share a recent common ancestor.

B. Systematics: Connecting Classification to Phylogeny. To trace phylogeny or the evolutionary history of life, biologists use evidence from paleontology, molecular data, comparative anatomy, and other approaches. Tracing phylogeny is one of the main goals of systematics, the study of biological diversity in an evolutionary context.

A tool that has revolutionized, and continues to revolutionize, phylogenetic analysis is DNA sequencing. With DNA sequencing, rather than using physical or behavioral features of organisms to build trees, we can instead compare the sequences of their orthologous (evolutionarily related) genes or proteins.
