Convergent Evolution - Analogous Structures
-
The flippers of the Penguins and Dolphins are the example of theFlippers of penguins (birds) and dolphins (mammals) perform similar functions but are anatomically different in origin – they are analogous structures. Analogous structures are a result of convergent evolution: different structures evolving for the same function and hence having similarities.
Hardy-Weinberg Equilibrium and Factors Disturbing It
-
Which one of the following factors will not affect the Hardy-Weinberg equilibrium?Five factors affect Hardy-Weinberg equilibrium: gene migration (gene flow), genetic drift, mutation, genetic recombination and natural selection. A constant gene pool means no change in allele frequencies, so it does not affect (disturb) the Hardy-Weinberg equilibrium.
Sequence of Human Evolution
-
Given below are some stages of human evolution. Arrange them in correct sequence. (Past to Recent) A. $Homo\ habilis$ B. $Homo\ sapiens$ C. $Homo\ neanderthalensis$ D. $Homo\ erectus$ Choose the correct sequence of human evolution from the options given below:The correct sequence of human evolution from past to recent is: $Homo\ habilis \rightarrow Homo\ erectus \rightarrow Homo\ neanderthalensis \rightarrow Homo\ sapiens$ i.e. A-D-C-B.
Geological Eras and Dominant Life Forms
-
Match List-I with List-II regarding geological eras and their dominant fauna.
Pick the matching item from Column II for each row.
Column I
- A. Mesozoic Era
- B. Proterozoic Era
- C. Cenozoic Era
- D. Paleozoic Era
Column II
- I. Lower invertebrates
- II. Fish & Amphibia
- III. Birds & Reptiles
- IV. Mammals
Correct answer: A → III, B → I, C → IV, D → II
Mesozoic Era – birds and reptiles Proterozoic Era – lower invertebrates Cenozoic Era – mammals Paleozoic Era – fish and amphibia Correct match: A-III, B-I, C-IV, D-II.
