There are a lot of animals in nature, which live on the
trees. This sort of living fits better to the animals that don't
have defense devices and keep them from reach of their enemies.
Up the trees is food for them and they use leaves and fruits as
nutriments. Them fore some of animals spend most of their times
above trees. To name some koala, squirrels, and monkeys. One of
these animals, which live in the South America, is Three Toedslath,
which eats of fruit and leaf of trees. This animal hangs up side
down from trees when resting.
At past times also were animals that used to live so. One of them
was Megatherium, which would have been living in South America, and
perhaps he was ancestor of the modern lazy animal. But he had a
noticeable difference with this one. It was as tall as five or six
meters and a mammal, which was similar to his modern type with 4
hands and feet. Fatty and over weight of such a heavy weight animal.
This is a question raised by scientists.
Short and fat feet, strong tail, little with strong neck and long
stiff hairs indicate that he just like modern lazy animals used to
live on the trees. So we face a dilemma which is true? His heavy
weight or his semblance to animals living on trees. Scientists
believe at its over weight and Orem. That despite its physics has
developed to live on tree. It used to move slowly on earth and by
bending the branches of trees eat of their nuts and fruits. It looks
like to say that modern lazy animal does not climb trees and live
only on earth, but in this case all of them fall prey to other
animals very soon. So how we are able to answer this question?
If we believe in increase of earth's pulling force, we can easily
answer this question. Though megatherium had a big body but its
weight was not too much so that branches were able to bear its
weight as its resting-place. Scientists calculate the weight of
megaterium considering its colossal weight but the mistake they make
at their calculation is that they use the present high attraction
force of earth. Which gives a big weight figure and concluding that
it is unbearable to branches. But earth's gravity force was less
than today and the calculation must be done by using them gravity
force, which gives lesser weight bearable to branches, so that they
were able to live on trees. Later on proper their body little by
little to the size of their today. Descendants who we know them as
lazy three finger (Toged slath).
Thus we see that to accept the increase in earth's gravity force
help us answer a great deal of questions, even we can answer some
questions which we were not able earlier, left without an answer.
