Well, at first, the monkey wouldn't know that whether the new tree is strong enough to hold itself. Initially, a monkey may not know if a new branch can support its weight.（简化句子并修正语法错误。）

So what it will do is to grab the trees already on and use its tails to wrap around the branch so that they wouldn't fail because the tail will save it. Therefore, it will grip onto the current branch and use its tail to wrap around it for additional support, preventing falls due to its tail's strength.（重组句子以提高连贯性和语法准确性。）

Another adaptation is about an ocular vision, which means that it can judge the distance between objects by judging how far apart from one branches. Another adaptation is their binocular vision, which allows them to judge distances between objects, such as the distance between branches.（修正"an ocular vision"为"binocular vision"，并调整句子结构。）

So they can determine how to jump. This helps them determine how far they need to jump.（调整句子以提高连贯性。）

Revised Answer (140 words):

In this lecture, the professor discussed two adaptations that primates, such as monkeys, have developed for living in trees. The first adaptation is their ability to firmly grasp and hold objects. For example, when monkeys move from one tree to another, initially, a monkey may not know if a new branch can support its weight. Therefore, it will grip onto the current branch and use its tail to wrap around it for additional support, preventing falls due to its tail's strength. Another adaptation is their binocular vision, which allows them to judge distances between objects, such as the distance between branches. This helps them determine how far they need to jump. These adaptations enable arboreal primates to navigate their environment safely and efficiently.
