The correct answer would be TRUE. Both the internal and external environments can modify or alter a gene. Epigenetics is the study of the changes in organisms caused by the modification of gene expression. According to epigenetics, environmental conditions can indirectly affect our DNA. An example would be an exposure to a chemical agent or toxin, that may enter the cells of the tissue and interface directly with the genetic material. In addition, stress can also affect the modification of the genes.

Según la historia evolutiva y sus diferentes saltos, ¿Qué linaje de especies es más antiguo?

Arturiano [62]

es la A

Hace aproximadamente 250 millones de años ocurrió la extinción masiva del Pérmico-Triásico, un evento en el cual murieron hasta el 96 por ciento de las especies marinas y un porcentaje similar de las terrestres. Cerca de tres millones de años después se produjo la separación, a partir de un ancestro en común, de los linajes que con el tiempo darían origen a las aves y los cocodrilos. El grupo que incluye tanto a cocodrilos como aves se lo denomina Archosauria, que significa ‘reptiles dominantes’.
