Opposable thumbs allow us to grasp and manipulate tools in a much easier fashion(as opposed to having to use our mouths, tails or more primitive grasping appendage), and gives us the ability to build and use them in very intricate/complex ways. This, coupled with a larger then average brain, allows us to drastically manipulate our environment in order to make survival much easier.
No, They Don't have an opposable thumb But a chimpanzee does!
No, mice do not have opposable thumbs. They have paws with a pollex, which is the innermost digit of the forelimb.
Siamangs have an opposable thumb on their hands, which allows them to grasp objects firmly, similar to humans. They also have an opposable big toe on their feet, which enhances their ability to grip branches and move through the trees with agility.
as far as ours can go
Humans (if being considered) do have the the most effective opposable thumbs. Next in line would be our close relative the chimpanzees
Having an opposable thumb is unique.
Basically, opposable thumbs are important to help us, primates, and panda bears, help grip things better, pick things up, and eat with one hand.We need opposable thumbs to do..well...to do almost everything!
The thumb and pinky are opposable digits, meaning they can touch each other, allowing for a wide range of movement and grip. This opposable positioning enables precision and dexterity in tasks such as grasping objects and manipulating tools.
Modern humans have opposable thumbs but not opposable toes.An opposable thumb means that you can touch the tips of your other fingers with the tip of your thumb, but not with any of the other fingers. This allows you to hold and manipulate objects with more precision.An opposable big toe is similarly useful for gripping objects with the feet. This would be particularly useful for an animal which climbed trees, as our ancestors did.See http://en.wikipedia.org/wiki/Thumb
The advantage of an opposable thumb is to grab things. It essentially puts us high on the food chain (next to our adaptable brain). It allows us to climb, grab, hold, catch, play thumb wars (among other things). -Brett
Convergent evolution occurs when unrelated species evolve with similar features. An example of this is opposable thumbs, which primates typically have. Opossums also have an opposable thumb, and they are not from the primate family.
The plum is a fruit that can be eaten fresh or used in cooking and baking. The thumb is one of the fingers on the human hand that is opposable, allowing for grasping and gripping objects.
