evolution paints human ancestors covered with fur.
fur has several benefits as stated by britannica "the pelts of fur-bearing animals are called true furs when they consist of two elements: a dense undercoat, called ground hair, and longer hairs, extending beyond that layer, called guard hair.
the principal function of ground hair is to maintain the animal’s body temperature; that of guard hair is to protect the underlying fur and skin and to shed rain or snow.".
Ruby - The paper is full of many facts.
The text of the paper describes the significance of the facts. The authors provide their results of a carefully constructed model.
They compare their conclusions with other possible explanations regarding the relationship between loss of fur and bipedal posture.
The paper was peer-reviewed by the National Academies of Science. They are not in the habit of publishing fact-free "just-so stories".
If you can see a flaw in the paper write to the NAS.
we like to think we are logical and have good reasons for for our beliefs.
no more so than when it comes to our reasons for rejecting the truth claims of jws.
we reject their version of history, such as the date of the fall of jerusalem, because it doesn't agree with the historical evidence.
who is she addressing her words to? - Ruby
Ruby, learn what words mean - Viv
I think there might be a clue there.

jocobm - You have misunderstood survival of the fittest.
The snake who reproduces is by definition the fittest.
Ruby - As usual you have thrown a meaningless word-salad at a science topic.
this site is great, i have been lurking for a while now.
but i can’t get reinstated and have used some of the advice already given.. i was df’d many months ago and go to all the meetings and do all the preparation for the meetings, but the jc committee keep refusing me.
tomorrow at the clam meeting i am puting yet another letter in and will be called for another dreadful jc meeting.. 1. what can i say to the elders to show that i am truly repentant?.
Welcome to the forum Betty.
I have to ask why on earth you would want to go back to a controlling organisation or allow those men to have any power over you?
There is no holy spirit - otherwise why have elders repeatedly appointed men who turned out to be pedophiles and adulterers as fellow elders? It is just a bunch of mostly uneducated men on an ego-fuelled power trip.

Well that is way off topic.
I don't understand your question?
Why do you think the mating habits of Garter snakes presents a challenge to evolution? How many species can you think of where the males compete for breeding rights?

Why don't you just send your critique to the most qualified scientists in the USA at the National Academy of Sciences since they were the ones who peer-reviewed and published the paper.
Be sure to tell them how you modelled heat loss based with varying time of day, fur covering and posture and why your results contradict Rixton & Wilkinson.
I look forward to reading the retraction by the NAS based on your research.

Yes and yes.

See this paragraph in particular..
Specifically, our model predicts that once hair loss and sweating ability have evolved to near-modern human levels, a hominin could thermoregulate even under hot, sunny conditions and even when involved in something as energetically demanding as brisk walking. Further, our calculations make predictions as to how the evolution of such hair loss and sweating ability might be linked to daily behavioral patterns. Specifically, it is clear from the extremes of hairiness that we simulated that progressive hair loss (in the absence of specialist adaptations to maximize sweating ability) would have led to even greater risk of overheating in the heat of the day (compared with a hairier individual), but would have made it easier to have been active nearer dusk and dawn. This could have provided selection pressure for hair loss, combined with behavioral adaptations such that long-distance travel under hot, sunny conditions was constrained to occur only early and late in the day. Once hair loss and sweating ability have evolved increasingly toward near-modern human levels, this temporal restriction would have progressively decreased, until eventually such exercise was even possible (providing sufficient water was available to allow replenishment of reserves) in the hottest part of the day.
