Overview

Las chinches de cama puede parecer un viejo problema pasado de moda, sin embargo ahora están de vuelta — y con venganza. Hace cincuenta años, estas plagas chupadoras de sangre estaban casi erradicadas en los Estados Unidos gracias, en parte, al uso de pesticidas como el DDT. Hoy, se arrastran entre las sabanas — y atormentan a los desgraciados soñadores — en todo el país...

  • [Mechanisms of evolution: Grades 9-12] There is variation within a population. (LS3.B)
  • [Mechanisms of evolution: Grades 9-12] Mutations are random.
  • [Mechanisms of evolution: Grades 9-12] Inherited characteristics affect the likelihood of an organism's survival and reproduction. (LS4.B, LS4.C)
  • [Mechanisms of evolution: Grades 9-12] Traits that confer an advantage may persist in the population and are called adaptations. (LS4.B, LS4.C)
  • [Mechanisms of evolution: Grades 9-12] Over time, the proportion of individuals with advantageous characteristics may increase due to their likelihood of surviving and reproducing. (LS4.B, LS4.C)
