While
the author of the reading passage argues that there are three reasons that
explain why the Argentavis mangificiens, giant ancient birds, could not fly,
the lecturer opposes the reading’s assertion with counter views.
First
of all, the lecturer contends that the claim regarding wings is baseless.
Although the Argentavis mangificiens could not flap their wings because hitting
the ground, they would find different ways to fly. To explain, the birds could
jump off of higher places such as a top of mountain or an edge of cliff, which
allowed them to fly without clapping. This casts doubt on the reading passage’s
argument that the Argentavis magnificens’ wings were too long to take off from
the ground.
Additionally,
the speaker points out that the assertion concerning muscles of wings seems
flawed. The wing muscles of the Argentavis magnificens were not strong enough
to flap after jumping off for the flight. However, they could glide without
flapping their wings like eagles. Thus, the muscles did not have to be sturdy.
This contradicts the reading passage’s assertion that the Argentavis magnificens
could not soar up to the sky because their wings were very lengthy in size.
Finally,
the professor asserts that the opinion that the Argentavis manificens did not
need to fly looks mistaken. Their body size was huge so that they would not
have depended on the flight to avoid any predator or hunt their preys. On the
contrary to this, they would fly so as to find their preys, developing their
wings for the flight. This goes against the idea presented in the reading
passage that the Argentavis magnificens were not able to lift off because they
were not in need of flying to flee from their predators or capture animals they
feed on. |
