Q. No.The extinct human who lived 100000 to 40000 years ago, in Europe, Asia, and parts of Africa, with short stature, heavy eyebrows, retreating for heads, large jaws with heavy teeth, stocky bodies, a lumbering gait, and stooped posture was:
1. Homo habilis
2. Neanderthal human
3. Cro-Magnon humans
4. Ramapithecus
1. Shortening of jaws
2. Binocular vision
3. Increasing brain capacity
4. Upright posture
Darwin's finches are a good example of:
1. industrial melanism
2. connecting link
3. adaptive radiation
4. convergent evolution
In the case of peppered moth (Biston betularia), the black-coloured form became dominant over the light-coloured form in England during the industrial revolution. This is an example of:
| 1. | natural selection, whereby the darker forms were selected |
| 2. | appearance of the darker coloured individuals due to very poor sunlight |
| 3. | protective mimicry |
| 4. | inheritance of darker colour character acquired due to the darker environment |
Peripatus is a connecting link between:
1. Ctenophora and Plantyhelminthes
2. Mollusca and Echinodermata
3. Annelida and Arthropoda
4. Coelenterata and Poriphera
1. Weismann - Theory of continuity of germplasm
2. Pasteur -- Inheritance of acquired characters
3. de Vries -- Natural selection
4. Mendel -- Theory of pangenesis
1. adaptive radiation
2. seasonal migration
3. brood parasitism
4. connecting links
1. analogous organs
2. homologous organs
3. vestigial organs
4. retrogressive evolution
| 1. | There is a decline in population as boys marry girls only from their own tribe |
| 2. | Hereditary diseases like colour blindness do not spread in isolated populations |
| 3. | Wrestlers who develop strong body muscles in their lifetime pass this character on to their progeny |
| 4. | There is no change in population size as they have a large gene pool |
One of the important consequences of geographical isolation is:
1. no change in the isolated fauna
2. preventing speciation
3. speciation through reproductive isolation
4. random creation of new species
