Pentadcatyl limb is a limb that have five did gets such as if you look at the human hand you can clearly see that you have five didgets .However looking at certain animals you wouldn't think that they have a Pentadcatyl limb such as animal The whale of the horse because they only have one didget but they have a Pentadcatyl limb but the reason you cant see it is because they have evolved to not have one on show but like the horse their Pentadcatyl limb is higher up the leg.

The Pentadcatyl Limb In a horse:
The horse is a mammal and it has for limbs. The four limbs have been adapted to help the horse run. Although looking at the horse you would not think that the horse had a pentadcatyl limb this is because they only have one didget which is the hoof. Originally the horse wasn't the size that we have today. The horse used to be really small this is because it didn't need to be tall because the human race has evolved them because we needed them to be able to run long distanced. However over this period of time the 5 didgets that the horse had it had changed into the hoof that we see today this was because then the horse would be able to walk on rough terrain easier. Although we cant see the pentadcatyl limb the horse still has it today it is just that it is placed further up the leg of the horse.

The Pentadcatyl Limb in a Bat:
The bat is a mammal and it has for limbs. The four limbs have been adapted to help the bat fly and hold on while they are sleeping upside down. Although looking at the bat you would not think that the bat had a pentadcatyl limb this is because they have wings but if you pull the wings out in the dark and put a light behind it then you will be able to see the pentadcatyl limb. The bats wing is that same as the humans hand and forearm. The pentadcatyl limb is bone however for the bat to be able to fly they have a thin layer of membrane. Scientists think that the bat has evolved from living in tree tops and gliding like the flying squirrel instead of flying. When gliding the bat would extend and thin the skin, as well as the bones this would help them glide everywhere. The theory is that the bat could have been able to run and leap of the ground before the bat evolved.
