The construction of phylogenetic trees is a mapping out the proposed divisions and common ancestors of all living species. Traditionally, these trees
have been built using morphological data, such as appearance and embryology. Recently, it has been possible to construct these trees using molecular
data. Phylogenetic trees based on different types of information agree with each: that there is strong evidence of a real underlying common descent
This phylogenic tree is composed based on molecular data (TRNA). What statements can we infer are true about the organisms throughout the tree?
Because the tree is rooted all branches share a common ancestor
All organisms have some sort of cellular structure/organization
All Eukaryotes evolved from Bacteria
Since the organisms contain RNA they share the same DNA
If the organisms contain RNA the share the same four nitrogen bases

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
