Do you ever wonder why we have fingerprints and just on our hands and feet? I chose this topic when the question came up in science: why do we have fingerprints and why just on our hand and feet? I thought that it would be interesting to learn about and spread the word about. Here is some information about the skin on your palms on your hands and feet: First, we don't have any hair on the palms of our hands and feet, even areas that you wouldn't think would have hair has at least the smallest amount (except the palms of hands and feet). Also there are many sweat glands. There is much less pigment in our palms of hands and feet. This skin is about 8-14 times thicker so the skin doesn't tear or wear down. Now here's what fingerprints are: They are tiny ridges or grooves on the surface of the skin and epidermis, these grooves are formed by lines in the dermis. Fun Fact: Did you know that fingerprints probably give us better grip by making friction and they could help the skin from tearing easily. Another Fun Fact: We are born with the same fingerprints we have through our whole lives. Now Here's a Question For You: Do you think that identical twins have the same fingerprints?
I have heard that identical twins have the same finger prints! Although I think they don't. I never knew that finger prints could give you better grip!
ReplyDeleteGood guess! I would tell you the answer but I want other people to guess before I tell the answer.
ReplyDeleteThis was a great post because I was wondering why we have fingerprints. This answers all my questions except one, do we have different finger prints per finger or are they all the same? I think twins do have the same finger prints...
ReplyDeleteGood question I'll try to find that out.
DeleteNo, we have different finger prints on each finger. I assume there has been a person who has had two or moar of the same. Good guess tho!

ReplyDeleteIt says that we don't have the same fingerprints on each of our fingers.
I liked that you ended your blog with a question. Good idea and great question
ReplyDeleteI think that identical twins do have the same fingerprints because they are identical right?
ReplyDeleteI liked the format of your blog. It's a good idea to put fun facts and a question at the end!
