5. La capacidad que tenemos las personas de ver la vida en colores tiene una directa relación con la evolución genética. la visión en color se produce a través de unas proteínas que se llaman oxinas, presentes en las células de nuestras retinas. Producidas por 3 genes, éstas nos permiten ver en rojo, verde y azul, así como los colores y matices resultantes de la combinación de estos colores. Usted que opina y en que se basaría para afirmar o controvertir tal argumento.

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.
