| Biology | Evolution | NEET exams |
| Evolution | |
| Miller-Urey experiment | Chemical origin of life
Electric discharge in a container with CH4, H2, NH3 and water vapour at 800℃ |
| Alexander Oparin | Written the book “Origin of life”
Oparin and Haldane proposed that life existed from organic molecules |
| Divergent evolution | Evolution from common ancestry due to different adaptations
E.g. Homologous organs, forelimbs of mammals, vertebrate heart, brain, tendrils and thorn or Cucurbita, Bougainvillea, etc. |
| Convergent evolution | Similarities in the different structures due to performing the same functions
E.g. Analogous organs, wings of birds and butterflies, eyes of octopus and mammals, root and stem modifications in sweet potato and potato |
| Adaptive radiation | Diversification of a species into new forms due to environmental changes and resource availability
E.g. Finches in Galapagos island, marsupials in Australia |
| Hugo De Vries | Mutation theory of evolution
He worked on evening primrose Saltation- single step large mutation causing speciation |
| Population genetics | Study of gene frequency in a population
Gene frequency- the proportion of alleles of a gene in the population |
| Hardy Weinberg Principle | The allelic frequency in a population remains constant
Factors affecting genetic equilibrium are- gene migration, genetic drift, mutation, recombination and natural selection p2 + q2 + 2pq =1 p2 = AA, q2 = aa, 2pq = Aa |
| Founder effect | Reduction in genetic variation, when a small group of individuals get isolated from a large population |
