Which of the following statement about the Theory of Special Creation (TSC) is correct?
-In contrast to evolution, TSC believes that all the estimated >100 million species on earth were created individually and separately.
-TSC also states that, since their creations, these species have remained the same forms without much change.
-For TSC, only a very short time has elapsed since the creations of all the species on earth.
-TSC does not believe that these millions of species shared a common ancestor.
-All of the above
Biological evolution is defined as a change in the
of a species over time.
survival rate
genetic makeup
number of individuals
number of offspring
Natural selection can be defined as:
chance differences in organism traits.
the chance for species numbers to increase rapidly.
the processes that lead individuals to resemble their parents.
the differential survival and reproduction of individuals.
the genetic fixation of species.

Group of answer choices inheritance of acquired characteristics competition for food and space variation among species survival and reproductionarrow_forwardThe theory of evolution is most accurately described as... Just an opinion that some scientists hold about how living things change over time. An educated guess about how species originate. An idea about how acquired characteristics are passed on to subsequent generations. One possible explanation, among several scientific alternatives, about how species have come into existence. An overarching explanation, supported by much evidence, for how populations change over time.arrow_forward

- Indicate which of the statements below is True or False. Enter 1 for True and 2 for False. Question 2 options: Evolution can be described as changes in the proportion of variable traits (including different alleles) within a population over generations. Morphological variation between individuals is almost always correlated with genetic variation, ie. those individuals that differ in phenotype also differ in genotype. Variation in morphological traits may be due to genetic or environmental factors, but both causes of variation can be inherited and be subject to evolutionary change. Phenotypic plasticity is the term used to describe plastic, or variable, responses by individuals with the same genotype under differing environmental conditions.arrow_forwardScientists often talk about the evidence for evolution. Using the five types of evidence listed here, explain how each suggests the occurrence of evolution: 1) structural homologies, 2) molecular homologies, 3) developmental homologies, 4) fossils (general) and 5) transition fossils.arrow_forwardWhat causes variation among a population of living things and How can variation in one generation influence the next generation? Is the variation in a population will be examined as the “raw material” upon which natural selection acts. Why are there so many different kinds of living things? Comparing species that exist today reveals a lot about their relationships to one another and provides evidence of common origins. This session explores the theory of evolution: change in species over time.arrow_forward
