The annual world seafood catch grew from approximately 19 million tons in 1950 to approximately 90 million tons in 1997. as a consequence, there has been a dramatic decline in the commercial fish populations. what could be a possible successful policy solution to the fisheries problem? develop fish hatcheries and release more fish into the ocean. ban commercial fishing until sustainable levels have been achieved. inform the general public to reduce the impact of recreational fishing. place international limits on the number of fish countries can take.

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 (rrna). 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.
