Palaeontological evidence for evolution refers to the:
1. | development of the embryo | 2. | homologous organs |
3. | fossils | 4. | analogous organs |
The appearance of antibiotic-resistant bacteria is an example of:
1. adaptive radiation
2. transduction
3. pre-existing variation in the population
4. divergent evolution
Fossils are generally found in:
1. | Sedimentary rocks | 2. | Igneous rocks |
3. | Metamorphic rocks | 4. | Any type of rock |
Which type of selection explains industrial melanism observed in moth, Biston betularia?
1. | Stabilising | 2. | Directional |
3. | Disruptive | 4. | Artificial |
In 1953, S. L. Miller created primitive earth conditions in the laboratory and gave experimental evidence for the origin of the first form of life from pre-existing non-living organic molecules. The primitive earth conditions created include:
1. | low temperature, volcanic storms, an atmosphere rich in oxygen |
2. | low temperature, volcanic storms, reducing atmosphere |
3. | high temperature, volcanic storms, non-reducing atmosphere |
4. | high temperature, volcanic storms, reducing atmosphere containing CH4, NH3 etc. |
According to Oparin, which one of the following was not present in the primitive atmosphere of the earth?
1. | Oxygen | 2. | Hydrogen |
3. | Water vapour | 4. | Methane |
The differential success in the reproduction, of an organism, in a given environment, is :
1. | Adaptation | 2. | Natural Selection |
3. | Adaptive radiation | 4. | Saltatory evolution |
Which of the following types of natural selection reduces variation but does not change the mean value?
1. | directional | 2. | stabilizing |
3. | disruptive | 4. | all of these |
The wings of birds, the forelegs of a horse, and the upper limbs of humans are:
1. | analogous structures | 2. | homologous structures |
3. | vestigial structures | 4. | phylogenetic structures |
The “Biogenetic Law” was given by :
1. | von Baer | 2. | Ernst Haeckel |
3. | Hugo de Vries | 4. | Theodosius Dobzhansky |
