Question
Here is the question : EMUS’ WINGS ARE CLASSIFIED AS WHAT?
Option
Here is the option for the question :
- Vestigial
- Homologous
- Speciation
- Resilient
The Answer:
And, the answer for the the question is :
Explanation:
Avestigial structures are body parts, such as the wings of some non-flying animals like emus and kiwis, that have no functional purpose. These structures once served a purpose, but they no longer do so as a result of adaptation and development. Wisdom teeth and the palmaris longus muscle, which extends between the wrist and elbow and was once useful for hanging grip, are examples of vestiges found in humans. Today, 10% of people lack this muscle entirely.
Emus are large flightless birds that are native to Australia. While emus have wings, they are classified as vestigial, meaning that they are no longer functional for flight. Instead, emus use their wings for balance and stability while running.
Vestigial structures are remnants of organs or structures that were once functional in an organism’s evolutionary history, but have since become reduced in size or lost their original function. In the case of emus, their wings are a vestigial structure that have evolved over time to better suit their environment and way of life.
Emus are adapted to life on the ground, where they use their long legs and powerful muscles to run at high speeds. Their wings have become reduced in size to make them more streamlined and efficient while running, and they no longer have the necessary musculature and feathers required for flight.
their wings still play an important role in their survival. emus also use their wings to communicate with other birds and to regulate their body temperature.
The presence of vestigial structures in organisms is an important part of the study of evolution. By examining these structures, scientists can gain insights into the evolutionary history of different species and how they have adapted to their environment over time.
emus’ wings are classified as vestigial because they no longer serve their original purpose of flight. Instead, they have evolved to better suit the emus’ ground-dwelling lifestyle, providing balance, communication, and temperature regulation. Understanding vestigial structures such as emus’ wings is essential for understanding the complex process of evolution and how organisms adapt to changing environments over time.
