Vermiform appendix in man, nictitating membrane and wisdom teeth are
Vermiform appendix, nictitating membrane, and wisdom teeth in humans are considered vestigial organs. Vestigial organs are remnants of structures that had important functions in ancestors but are no longer useful in the same way.
Which one of the following terms would most correctly describe the relationship between the flight organs of animals like locust, bat, swallow, and flying fish ?
The flight organs of animals such as locusts, bats, swallows, and flying fish are considered analogous. This means they have similar functions (flight) but evolved independently in different species, indicating convergent evolution.
Appearance of facial hair in some people is an example of
Atavism refers to the reappearance of ancestral traits that had been lost through evolutionary changes. The appearance of facial hair in some people is an example of atavism because it is a trait that was present in our distant ancestors but is not commonly expressed in the modern human population.
Von baer supports the theory of evolution on the basis of
Von Baer supports the theory of evolution based on embryological characters. He proposed that the development of an embryo (ontogeny) recapitulates the evolutionary history (phylogeny) of the species. This concept helps in understanding the evolutionary relationships among different species.
Which of the following bird will be called most successfully evolved ?
Biogenetic law states that
The biogenetic law, also known as Haeckel's recapitulation theory, states that 'ontogeny recapitulates phylogeny'. This means that the development of an organism (ontogeny) expresses all the intermediate forms of its ancestors (phylogeny). Essentially, the stages an embryo undergoes during development resemble the sequence of its evolutionary ancestors.
A study of evolution has established the systematic positions in many animals. In some animals chordate characters are absent in adult stage, but present in larval stage, eg. Herdmania has been included in
Herdmania is a member of the subphylum Urochordata (also known as Tunicata), which is part of the phylum Chordata. In Herdmania, chordate characteristics such as a notochord and a dorsal nerve cord are present in the larval stage but are lost in the adult stage. This is why Herdmania is included in Protochordata.
Many of the animals and plants found on islands are
Many animals and plants found on islands are termed 'endemic'. This means they are native to a particular region or environment and are not found naturally anywhere else. The isolation of islands often leads to the development of unique species that evolve to adapt to their specific environment.
The Haeckel’s theory of biogenetic Law means that
Haeckel's theory of biogenetic law, also known as the recapitulation theory, states that the development of an organism (ontogeny) expresses all the intermediate forms of its ancestors throughout evolution (phylogeny). In simpler terms, the life history of an organism reflects its evolutionary history.
