The age of rock is calculated on the basis of
The age of rock is often calculated based on the amount of uranium present. This method, known as uranium-lead dating, relies on the radioactive decay of uranium isotopes into stable lead isotopes, providing a way to estimate the age of rocks that are millions to billions of years old.
All mammals, whale, dolphin, bat, monkey and horse have some common trait, but they also show conspicuous differences. This is due to the phenomenon of
The phenomenon responsible for the conspicuous differences in traits among mammals like whales, dolphins, bats, monkeys, and horses, despite having some common traits, is called divergence. Divergence refers to the process whereby groups from the same common ancestor evolve and accumulate differences, resulting in the formation of new species. This is driven by different selective pressures in different environments, leading to adaptations that are specific to those environments.
These are some examples of vestigial structures in man
In humans, vestigial structures are body parts that have lost most or all of their original function through evolution. Examples of vestigial structures in humans include the wisdom tooth, vermiform appendix, and coccyx. The wisdom tooth is a remnant from a time when human ancestors had larger jaws with more teeth to help chew foliage. The vermiform appendix is a leftover of a larger cecum that was used for digesting cellulose in the diet. The coccyx or tailbone is a vestigial remnant of a tail.
Precipitation test gives evidence from
The precipitation test gives evidence from comparative serology. Comparative serology is the study of similarities and differences in the blood serum of different species. The precipitation test involves mixing an antigen with its specific antibody, which results in the formation of a visible precipitate. This test can be used to determine the degree of similarity between proteins of different species, thereby providing evidence for common ancestry.
In external appearance the krait and lycodon are indistinguishable. This is an example of
Mimicry is a phenomenon where one organism evolves to resemble another organism for some advantage, such as avoiding predators. Kraits and lycodons appear similar externally, making it hard to distinguish between them, which is a form of mimicry.
Post anal tail can be traced in
A post-anal tail is a characteristic feature of chordates, which includes the Cobra. Earthworms, scorpions, and centipedes do not belong to this group and do not have a post-anal tail.
The Jurassic period belongs to the_________ era.
The Jurassic period is part of the Mesozoic era, which is known as the age of reptiles and dinosaurs. The Mesozoic era is divided into three periods: Triassic, Jurassic, and Cretaceous.
Which of the following cannot determine phylogenetic relationships ?
Mark the correct set. Column I I. Slow evolution II. Environment is responsible for evolution III. Homologous IV. Analogous organ Column II A. Non-progressive B. Aristotle C. Bird wing and butterfly wing D. Wing of bird and hose limb
The correct set matches concepts with their corresponding descriptions: I. Slow evolution – A. Non-progressive, II. Environment is responsible for evolution – B. Aristotle, III. Homologous – D. Wing of bird and horse limb, IV. Analogous organ – C. Bird wing and butterfly wing.
A. Ear muscles of external ear in man are poorly developed R. These muscles are useful which move external ear freely to detect sound efficiently.
