Re: [Goanet] Evolution (contd)
Hi Peter, Your latest post under the above thread did appear on Goanet (Please see the archives). Therefore, I am posting this reply. Here are my responses to your points. Peter D'Souza wrote: You are incorrect in stating that he assumed a constant_ growth rate. In fact, this is what he did say: although it is obvious that the present rate of growth (2%) could not have prevailed for very long in the past, it does seem unlikely that the long-time growth rate could have averaged significantly less than (1/2)%. I don't know whether you have a mathematics background or not. But if you tried to understand the math behind how you calculate a population change based on a variable growth rate (i. e. positive growth as well as negative growth or decline) then you would realize that the formula used by Morris assumes only a constant positive growth rate. He also assumes a constant average growth rate from 1800 to all the way back to the origin of man. You cannot simply average positive and negative growth rates, and use the average in the formula. There are good estimates that in the last 2000 years there were at least two periods when there was a negative growth rate (decline). Nobody has the slightest idea of the directions of population changes during the 4000 years prior to that. It is very likely that because of high infant mortality rates there was 0% growth or negative growth during some phases of this era. A real scientist with knowledge about the math involved would never have attempted to do the type of calculation that Morris attempted. One cannot derive a formula for this because one has absolutely no knowledge of when the population increased and when it decreased, and by how much, before 200 B.C. It is next to impossible to derive a realistic combination formula for variable increases during some variable periods and variable decreases at other variable periods. People have written hundreds of papers using all kinds of mathematical models on this subject. He seems to believe that one man or couple might have been in existence 8,000/10,000/6,300 years ago and that such a man's contemporaries were destroyed. This seems rational, given his mindset. I'm surprised that you wouldn't agree but choose to dispute population growth rate instead. Please read your first Goanet post on your friend's argument. What you stated in that post emphasizes the 2% population growth, and mentions that your friend's estimate is an extrapolation based on that growth rate, allowing for some natural disasters. This original argument is similar to that of Morris, and is mathematically flawed, as shown above. It does not appear to me to be a genuine scientific argument at all. Perhaps, you misunderstood what your friend was saying. If you tell me his name, I could check if he has published his calculation in any scientific journal. If he has not published it, it is unlikely to be a serious, well-researched argument. I would not use the words real and estimates in the same sentence. I mean real scientific estimates as opposed to the pseudoscientific estimate of Morris. The same table says that the world population grew at 0% (zero percent) and stayed at exactly 5 million for a period of 3,000 (three whopping thousand)years. Are these guys serious? This was before the condom was invented. There is nothing unusual about 0% growth rate. I am sure you know that growth rate is birth rate minus death rate. If these two rates are equal then you have zero growth. If the death rate is more than birth rate then you have a decline or negative growth. In the old days the death rate was very high, especially the infant mortality rate. The latter rate was in some cases higher than 500 per 1000 live births. At this rate one needed a very high birth rate (more than 8%) in order to prevent extinction of mankind. This was very hard to do before large residential communities were established. People's life expectancy was also very low perhaps, in the twenties. So the reproductive life span was also very short. The people who contributed the data in the table provided by the U.S. Census Bureau are the worlds experts on population theory, history and statistics. They are certainly more knowledgeable and qualified than Morris. Please do not prejudge them without reading and understanding their research papers cited at the bottom of that table. If your friend has published a paper like that, please let me know. I can read his and their papers, try to understand and compare them, and see whose estimates make more sense. Radiocarbon dating, which depends on the steady decay of carbon-14, becomes less and less reliable once the artefact under study gets older than about 16,000 years. is what Dr. Chris Stringer, Natural History Museum, London, Radiocarbon dating is only one of many methods used for dating fossils and artifacts today. There are a whole bunch of other methods such as potassium-argon dating, geological dating,

What you state above refers only to SH the first couple of paragraphs of that article with SH quite revealing title of Evolution and the Population SH Problem. If you read the entire article, you will SH find that Morris makes an argument for a Biblically SH mandated recent origin of man based on a constant SH population growth rate. When I said: I don't think Mr. Morris was making a case for a 2% population growth rate I meant that his thesis was not to push a 2% growth theory, i.e. he wasn't making that his primary case, rather (you're right in this) his argument is for a biblical creation time line based on population growth rate. You are incorrect in stating that he assumed a _constant_ growth rate. In fact, this is what he did say: although it is obvious that the present rate of growth (2%) could not have prevailed for very long in the past, it does seem unlikely that the long-time growth rate could have averaged significantly less than (1/2)%. SH He gives a formula to SH calculate the number of years that have elapsed since SH the origin of man assuming that the entire human SH population emerged from one human couple created by SH God given whatever the actual value of the population SH of the world was around 1800 A.D. When he plugs in a SH population growth rate of 1/3% (not 2%) in the SH formula he gets a value of 6300 years for the origin SH of man. He says that this is consistent with what is SH inferred from the Biblical account. Correct. He is quite consistent in assuming the population growth rate to have been between 1/2% (an assumed low) and 2% (current). SH Here are some of SH the relevant quotes from his article that you seem to SH have missed somehow: Morris In that case, the length of time required for the Morris population to grow from 2 people to one billion [...] Morris Thus, the most probable date of human origin, based on Morris the known data from population statistics, is about Morris 6,300 years ago. The in that case was referring to the estimated population growth rate--based on the actual populations--between 1650 and 1800, which he uses to bolster his case. No, I didn't miss this. Again, he is not making up the 2% figure and also accommodates a growth rate as low as 1/3%. SH Please ask your friend where he got his fallacious SH argument for linking the population growth rate with SH the origin of man. I am willing to bet that it is from SH Henry Morris?s writings or their derivations. My friend would be very reluctant to say that man actually originated 6,300 years ago.

Like you, he believes the x million-year theories that have been floating around for the last century.
