The theory about the origin of life that holds that living creatures could arise from nonliving matter and that such processes were commonplace and regular is known as:
 
  •     Panspermia
  •     Divine or special creation
  •     Spontaneous generation
  •     Primary abiogenesis
Which of the following is not a basic point about Oparin-Haldane hypothesis?
 
  •     Early earth had a chemically oxidising atmosphere.
  •     This atmosphere, exposed to energy in various forms, produced simple organic compounds ("monomers").
  •     These compounds accumulated in a "soup", which may have been concentrated at various locations (shorelines, oceanic vents etc.).
  •     By further transformation, more complex organic polymers – and ultimately life – developed in the soup.
Consider the two statements:
I.    Birds and bats have homologous limbs.
II.    They are both ultimately derived from terrestrial tetrapods.
 
  •      Both I and II are correct and II explains I
  •     Both I and II are correct but II does not explain I
  •     I is incorrect but II is correct
  •     I is correct but II is incorrect
Examples of convergent evolution will include:
I.    Opposable thumbs in primates and giant pandas.
II.    Eye of cephalopods and vertebrates.
 
  •     Only I
  •     Only II
  •     Both I and II
  •     Neither I nor II
The statement “Embryos pass through successive stages that represent the adult forms of less complex organisms in the course of development” can be equated with:

  •     Punctuated equilibrium
Modern Homo sapiens arose:
