Which of the following is the relatively most accurate method for dating fossils?
1 Potassium-argon method
2 Uranium-lead method
3 Electron spin resonance method
4 Radio carbon method
Explanation:
Electron spin resonance dating is being utilized in fields like radiation science, natural chemistry and also topography prehistoric studies and human sciences. ESR dating is utilized rather than radiocarbon dating since ESR dating can date recently framed materials. It measures the number of unpaired electrons in crystalline structures that were exposed to natural radiation previously.

The method of representing phylogeny by branching diagram was introduced by
1 Lamarck
2 Darwin
3 Ernst Haeckel
4 Mendel
Explanation:
The method of representing phylogeny by branching diagram was introduced by Ernst Hoeckel. His specific diagrams and ideas have evolved and been refined over time. This method illustrate the evolutionary relationships and common ancestry among different species or groups of organisms.

Some bacteria able to grow in streptomycin containing medium due to
1 Natural selection
2 Induced mutation
3 Reproductive isolation
4 Genetic drift
Explanation:
Normally bacteria can not survive in antibiotic containing medium but if it does so it must have acquired resistance against that antibiotic. These are well adopted to grow in streptomycin, containing medium and thus are more evolved. So due to natural selection only the more evolved and better adapted species is able to survive.

Which of the following evidences does not favour the Lamarckian concept of inheritance of acquired characters?
1 Lack of pigment in cave-dwelling animals
2 Melanisation in peppered moth
3 Absence of limbs in snakes
4 Presence of webbed toes in aquatic birds
Explanation:
Lamarck is best known for his theory of Inheritance of acquired characteristics, first presented in 1801. An organism experiencing such a modification can transmit such a character to its offspring.
