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
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 |
1. adaptive radiation
2. seasonal migration
3. brood parasitism
4. connecting links
1. analogous organs
2. homologous organs
3. vestigial organs
4. retrogressive evolution
Among the human ancestors the brain size was more than 1000 CC in:
1. Homo neaderthalensis
2. Homo erectus
3. Ramapithecus
4. Homo habilis
The concept of chemical evolution is based on:
| 1. | crystallization of chemicals |
| 2. | interaction of water, air, and clay under intense heat |
| 3. | effect of solar radiation on chemicals |
| 4. | possible origin of life by a combination of chemicals under suitable environmental conditions |
| 1. | Thorn of Bougainvillea and tendrils of Cucurbita – Analogous organs |
| 2. | Nictitating membrane and blind spot in the human eye – vestigial organs |
| 3. | Nephridia of the earthworm and Malpighian tubules of cockroach - Excretory organs |
| 4. | Wings of a honey bee and wings of crow - Homologous organs |
Select the correct statement from the following:
| 1. | Darwin variations are small and directionless |
| 2. | fitness is the end result of the ability to adapt and gets selected by nature |
| 3. | all mammals except whales and have seven cervical vertebrae |
| 4. | Mutations are random and directional |
The finches of the Galapagos islands provide evidence in favour of:
1. special creation
2. evolution due to mutation
3. retrogressive evolution
4. biogeographical evolution
