Question

classify each of the following as examples of evidence of evolution as embryology (e); biogeography (b); phylogenetic tree (pt); or dna sequencing (ds). science uses many fields of study to provide evidence that evolution has and is taking place. what determinations can be made from the areas of dna sequencing, homology, embryology, and fossil record. check all of the determinations that these fields support: organisms share common ancestry, organism change over time, some species that lived are now extinct, current forms of species descended from ancestral forms, new species can develop from existing species

Explanation:

First Image (Biogeography - B)

Biogeography studies the distribution of organisms. The map - like image with organisms' distributions relates to how species are distributed geographically, which supports evolution concepts like species sharing common ancestry (as related species may be distributed in areas connected to their origin) and current species descending from ancestral forms (distribution patterns can show evolutionary spread). So it supports "organisms share common ancestry" and "current forms of species descended from ancestral forms".

DNA Sequencing looks at genetic codes. Similar DNA sequences between organisms support common ancestry, and differences can show evolution over time (organism change over time) and new species from existing (as genetic changes lead to new species). So it supports "organisms share common ancestry", "organism change over time", and "new species can develop from existing species".

A Phylogenetic Tree shows evolutionary relationships. It depicts how current species (tips of the tree) descend from common ancestors (nodes), and can show extinct species (branches that end without current species) and new species from existing (branching events). So it supports "organisms share common ancestry", "some species that lived are now extinct", "current forms of species descended from ancestral forms", and "new species can develop from existing species".

Answer:

• organisms share common ancestry: Checked
• current forms of species descended from ancestral forms: Checked
