  Evolution is a Fact #11 - Tiktaalik

  by cofty in

  1. watchtower
  2. beliefs

  one of the biggest gulfs that life has had to cross was the transition from sea to dry land.. fish have conical shaped heads, reptiles have flat heads.

  fish have no necks; their heads are attached to their shoulders by a series of bony plates.

  land-dwelling animals all have necks; their heads can move independently of their shoulders.

  Another modern example (possibly) of natural selection at work.

  This thread confirms my theory: Everything is funnier when uttered in a typical Southern US drawl. Try it sometime - just start talking like a Southerner. You'll make yourself laugh, guaranteed.

  I'm pretty much caught up on Cofty's fascinating series. Most of his entries have been interesting and illuminating.

  Or, perhaps I should write that as "illuminatin'."

  Evolution is a Fact #25 - Deep Time

  by cofty in

  1. watchtower
  2. beliefs

  in the 18th century the calculations of archbishop james ussher regarding the age of the earth were still accepted without question.

  according to ussher god made the earth at 6pm on the evening of saturday 22nd october 4004 b.c.. this naive certainty was to become a victim of the scottish enlightenment and the brilliant mind of james hutton.

  having qualified as a medical doctor in 1749 hutton returned to the family farm in berwickshire not far from where i am typing this now.

  Interesting, as all the posts in this series are, Cofty. Of course, aside of Young Earth Creationists, this doesn't apply much to JWs, who accept that the Earth is billions of years old. But a worthy read nonetheless.

  Evolution is a Fact #26 - Colour Vision

  by cofty in

  1. watchtower
  2. beliefs

  each little flower that opens,each little bird that sings,he made their glowing colours,he made their tiny wings.. all of us have been moved by the riot of colours in a spring meadow, the majesty of a sunset or the beauty of a bird in breeding plumage.

  what greater evidence could there be of a loving creator than our colourful world and the human eye that is equipped to appreciate it?.

  this is the sort of simplistic argument that convinces a lot of creationists about their beliefs.. it's time to "unweave the rainbow".. light is detected by a proteins called opsins.

  "what greater evidence could there be of a loving creator than our colourful world and the human eye that is equipped to appreciate it?."

  There are two ideas expressed in this quote: 1)We live in a colorful world and 2)We have eyes equipped to appreciate it.

  Actually, it's the brain that "appreciates it". But that point aside, I'd be interested in what mechanism is behind "appreciation". Is there a natural explanation for our "appreciation" of color?

  That question led me to this article, which seems to indicate that the jury is still out:

  Does Evolution Explain Human Nature?

  Evolution is a Fact #5 - Vitamin C

  by cofty in

  2. beliefs

  part 1 - protein functional redundancypart 2 - dna functional redundancypart 3 - ervspart 4 - smelly genes.

  in part 4 we saw that roughly half of the 800 genes in the human genome that code for olfactory receptors are broken remnants of our evolutionary history.

  they were vital to our distant ancestors but in humans, as in our primate cousins they have been allowed to fall into disuse as our eyes became more important to our survival than our nose.

  Interesting points in these threads as I catch up. For the record, I'm reading this as I eat a nectarine.

  #1 protein functional redundancycomparing the sequences of amino acids in ubiquitous proteins confirms the relationship between all living things.. #2 dna functional redundancycomparison of the dna that codes for the amino acids of ubiquitous proteins predicts the tree of life with an astonishing degree of accuracy.. #3 ervsendogenous retroviruses that infected our ancestors are found in the same place of the genome of our closest primate cousins.

  #4 smelly geneshundreds of broken genes that used to code for olfactory receptors in our ancestors are still found in our genome.. #5 vitamin cwhy humans can no longer make their own vitamin c and what that tells us about our species' history.. #6 human chromosome 2our second biggest chromosome is made up of two of our ancestors' genes stuck end-to-end.. #7 human egg yolk genehumans and our primate cousins have the genes for making vitellogenin and they are all broken in the same way.

  #8 jumping genesbits of parasitic code called alu elements prove our common ancestry with primates.

  Evolution is a Fact #29 - Use it or Lose it

  this is a small part of the southern side of an 18th century garden wall.

  my house is just outside the north-east corner.. it is impossible to look at this picture and not notice that this section didn't start life as a garden wall.

  we can clearly see the remains of a derelict house that has been incorporated into the garden.

  Interesting, Cofty. I'm going to have to go back and review the entries in your series that I missed.

  Worst Bible Verse ... EVER

  from the nwt, of course.

  none of the other versions make it sound any better, either.

  2 timothy, chapter 2 has been used and abused to suppress women everywhere.

  Many verses are going to look bad when examined in the light of Western cultural values. Back then, I would think, much of what we consider outrageous seemed quite normal.

  One problem that many have with the Bible - and it may well be a very valid criticism- is that the Bible seldom, if ever, lifts itself above the cultural norms of the day.

  I have what I would consider to be "Interests" but no real hobbies. Maybe I'm drawing too distinct a line between the two.

  For example, I have a gym membership and work out regularly. Yet, I consider that more of an interest than a hobby. But maybe that is a hobby?

  I guess I think of a hobby as more of something that one spends hours on and is meticulous about. I'm not terribly meticulous about fitness. I don't micro-manage my diet, for example, weigh foods and count protein grams, etc. To me, that's what would put fitness into the category of a hobby.
