Convergent Evolution | MCQs
مندرجہ ذیل میں سے کون سا مشابہ اعضاء کی مثال ہے؟
A. Wings of bat and bird
B. None of the above
C. Hand of man and leg of horse
D. Testis in male and ovaries in female developed from the same embryonic tissue
Explanation
Analogous organs have similar functions but different evolutionary origins. Wings of a bat (mammal) and a bird (avian) serve the same function (flight) but evolved independently . Show/Hide Explanation
A. Analogous structures
B. Fossils
C. Vestigial structures
D. Homologous structures
Explanation
Structures that have similar functions but evolved independently from different ancestral origins are called analogous structures.
Analogous structures are found i n different species that have adapted to similar environments or ways of life.
For example, the wings of a bird and the wings of an i nsect are analogous
They both allow for flight, but they evolved independently from different structures ( bones in bird wings vs. exoskeletal extensions in insect wings ).
Show/Hide Explanation
A. Convergent evolution
B. No evolution
C. Same origin
D. Divergent evolution
Explanation
The wings of birds and flying lizards are examples of convergent evolution, where different species evolve similar traits independently, often due to similar environmental pressures.
Show/Hide Explanation
ایک عام خصوصیت؛ ہموار جسم، مختلف فائیلا کے تیز تیراکوں میں پایا جانے والا ______ نامی ارتقائی عمل کا نتیجہ ہے؟
A. Parallel evolution
B. Convergent evolution
C. None of these
D. Divergent evolution
Explanation
Convergent evolution occurs when different species develop similar traits, like a streamlined body. Due to similar environmental pressures or lifestyles . This is seen in fast swimmers across various phyla, such as dolphins (mammals) and sharks (fish). Show/Hide Explanation
متضاد ارتقاء کی وجہ سے مماثلتوں کو ________ کہا جاتا ہے؟
A. None of these
B. Both A and B
C. Homoplasy
D. Analogy
Explanation
Homoplasy and analogy both describe similarities in traits due to convergent evolution, not shared ancestry. These traits evolve independently in different species to adapt to similar environments or functions. Show/Hide Explanation
