TIL humans have recently evolved new traits like the ability to free-dive, live in high altitudes, resist disease, lactase persistence, and others.

  1. Hear me out.

    When I first read this, I thought you were referring to our ability to jump off of buildings with parachutes. Base Jumping, or some ilk of body suit sailing.

    And I was thinking to myself… how the hell is that an evolved new trait?

    The ability to fall off a building and survive is pretty miraculous but not exactly Darwinian.

    But I digress. That’s a great TIL, thank you for sharing it.

  2. part of this article is out of date. 96% of the human genome does not have an unknown function. we’ve known for about a decade that most of the human genome serve regulatory functions. in this article it says 3% serves that function but its about 80%.

    also, theres a section that talks about the amount of time it takes for genetic changes to becomg ubiquitous in populations. theres ‘new’ research (also roughly 10 years old, oddly enough) that shows the amount of time it takes for genetic information from random mutations to become ubiquitous is quite long. this is for new information, not existing information.

    >Biologically realistic numerical simulations revealed that a population of this type required inordinately long waiting times to establish even the shortest nucleotide strings. To establish a string of two nucleotides required on average 84 million years. To establish a string of five nucleotides required on average 2 billion years. We found that waiting times were reduced by higher mutation rates, stronger fitness benefits, and larger population sizes. However, even using the most generous feasible parameters settings, the waiting time required to establish any specific nucleotide string within this type of population was consistently prohibitive.
