This video covers the reason behind
your skin wrinkling upon becoming wet. The reason is that when your fingers
becoming wet, blood vessels contract and pull the skin along with it, leaving a
wrinkled finger. The body has actually evolved for this to happen. The reason
is that wrinkly hands allow us to better grip things when we’re wet. This
allowed gathering and hunting in bodies water more practical, providing more
food and resources, thus giving a survival benefit. Natural selection caused
for it to be a trait of humans. Also, when on slippery surfaces, we run better
with wrinkled feet, so our feet do the same.
This relates to our science class
this term because it relates to the process of natural selection and how traits
that give a survival benefit pass on, such as how being able to grip things and
move better in water due to wrinkling provides humans an advantage, and
therefore it is passed on throughout the human species.
Does this trait imply that humans were adapted to "live" in a water habitat at one point in time?
ReplyDeleteWas this trait originally acquired from an evolutionary ancestor or as a mutation?
