Which of the following statements is FALSE about the long-term evolution experiment (LTEE) that you learned about in the Case Study 2 content? a) The LTEE is different from most other studies of evolutionary change within lineages because the "frozen fossil record" allows recovery and further study of ancestors that lived many thousands of generations ago. Ob) The LTEE shows that the evolution of a new trait may occur in several steps, the first of which is the origin of mutations that arise because someday they will make it possible for new traits to manifest and be selected for in a given environment. c) The LTEE reinforces the notion that whether a given mutation is beneficial or deleterious depends on the environment in which the organism lives. O d) The LTEE shows that traits can evolve independently and even repeatedly, but that there are also signs of historical contingency in that they do not necessarily evolve in exactly the same way from a genetic standpoint. e) The LTEE…

ONE OF THE STATEMENTS OF EVOLUTION THEORY OF CH. DARVIN IS Select one: adaptations of organisms have relative nature all species are adapted to different conditions of existence adaptations of organisms have absolute nature all species originated by means artificial selection
A reasonable definition for a species is: O A distinct kind of animal. O A group of living things with functionally similar traits, for example, all creatures that can fly. O A group of living things with taxonomically similar traits. O A group of taxonomically similar living things in which all healthy members can interbreed and produce fertile offspring. QUESTION 8 If microevolution is any change in the gene pool of a breeding population, then macroevolution is: O A change in the genetic makeup of group that eventually results in the development of a new species. O The mass exctinction of old species to make way for new. O Changes in the physical environment at large. O When microevolution happens on a large scale. * QUESTION 9 What is the primary cause of speciation? O Extinction. O Overpopulation. O Environmental change. O When a breeding population becomes reproductively isolated from its ancestral population, for a long enough time, in a different enough environment, that it…

The theory of evolution by Darwin is a composite theory, i.e. it has five component theories: 1. Evolution as such is the simple proposition that the characteristics of lineages of organisms change over time 2. Common descent is a radically different view of evolution than the scheme Lamarck proposed. Common descent is a concept in evolutionary biology applicable when one species is the ancestor of two or more species later in time. 3. Gradualism – Darwin’s proposition that the differences between even radically different organisms have evolved incrementally, by small steps through intermediate forms. The alternative to this theory, as discussed in later sections, is saltation with great reference to large differences that are believed to have evolved by leaps without intermediates. 4. Populational change – Darwin’s thesis that evolution occurs by changes in the proportions of individuals within a population that have different inherited characteristics. 5. Natural selection – Darwin’s…
