Storyboard Text

  • Asexual:Advantages:the population can increase rapidly when the conditions are favourable.only one parent is is more time and energy efficient as you don't need a is faster than sexual reproduction.
  • evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection.
  • Sexual:Advantages:produces genetic variation in the offspring.the species can adapt to new environments due to variation, which gives them a survival advantage.a disease is less likely to affect all the individuals in a population.
  • If an organism changes during life in order to adapt to its environment, those changes are passed on to its offspring
  • Lamarck
  • stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
  • Darwin
  • Modern evolution as the change over time in this genetic variation. The frequency of one particular allele will become more or less prevalent relative to other forms of that gene.
  • Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.
  • Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.
  • Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
  • Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
  • Embryology the branch of biology and medicine concerned with the study of embryos and their development.
  • Disadvantages:Negative mutations linger longer in asexual organisms. ...Diversity is limited. ...Population numbers can be difficult to control. ...There can be an inability to adapt. ...Overcrowding can be a real issue. ...Reproduction can create competition
  • Disadvantages : It takes time and energy to find a mate and reproduce. Reproduction through sexual means is uncertain. ...Favorable genetics might not be passed to the offspring. ...Fewer offspring are typically produced. ...It can be deadly.
