The Dilemma: To Believe in Darwin or The Minister?

 

 VIEWS ON THE DARWINIAN THEORY OF EVOLUTION


Key words: Darwinism, views of Indian minister and public, world view, misconceptions.

 INDIAN VIEW

A few years ago, a  junior minister of Human Resource Development  in the then Government of India claimed that Charles Darwin’s theory of evolution of man was “scientifically wrong”, and it needed to be changed in school and college curriculum. He said, “Nobody, including our ancestors, in written or oral, have said they saw an ape turning into a man,”…. further adding “No books we have read, or the tales told to us by our grandparents had such a mention” (The Hindu, January 20, 2018). About two years later, the same Member of Parliament again questioned Darwin's theory of evolution  saying human beings are descendants of sages and not monkeys as propounded by the British scientist (Times of India, Jul 19, 2019). 

It is an altogether different matter that Charles Darwin never claimed that “man was descended from the apes,” nor did he say that an ape turned into a man. Modern scientists would view such a statement as a useless simplification—just as they would dismiss any popular notions that a certain extinct species is the “missing link” between humans and the apes. In 1871 Darwin suggested in his book The Descent of Man that human beings shared a recent common ancestor with the great African apes.  Darwin’s assertion was based on the many shared anatomical features of apes and humans. In his Descent of Man,  he referred to  the natural processes leading to us, the Homo sapiens, dwelling at length on the special role of the secondary mechanism of sexual selection.  Darwin makes it very clear that he considers human thinking and actions, especially in the moral realm, have an evolutionary origin just as much as our physical nature. 

Notwithstanding the minister’s comment, a study conducted by group of evolutionary biologists from the Central University of Punjab, Bathinda, India (Blast and Tahilramani, 2018; Times of India, Aug 30, 2018)  revealed that 68.5% of Indians accepted that the human beings evolved  from earlier species of animals. The figures though are marginally less than in Iceland, Denmark, Sweden, France, and Japan, where over 78% accept evolution, are  significantly higher than that in many other countries including the United States and Turkey. According to Pew Research Analysis (2013), only 32% American adults accept evolution of human beings through natural processes, while 33% of the whole population entirely reject it. 

Countries where religious belief is high (Turkey, US etc.) tend to be least likely to accept the evolution, and vice versa. Paradoxically,  the Indian population is thought to be highly religious, with the 2011 census revealing 99.8% of the population to be part of major religions in the country; merely 0.2% had no religion. According to  Bast and Tahilramani (2018), the  possible reason for high public acceptance of evolution in India despite the fact of high religiosity is that Hinduism, the major religion in India,  is not in conflict with Darwin’s theory of evolution to a large extent. Most Hindus accept the theory of biological evolution, as similar concepts like the concepts of dashavatara (ten incarnations of Lord Vishnu)  have existed in India since time immemorial. 

But as one goes behind these numbers to ask what the  Hindus actually mean when they say that they accept the theory of evolution, the story gets more complicated.  As noted by Nanda (2010), it becomes evident from reading the writings of professional Hindu gurus, sages and philosophers and following public perception that   “evolution”  in this case does not necessarily mean Darwinism. While Darwinian theory explains evolution of species by descent from a common ancestor by genetic modification, Hindu teachings assume spirit or consciousness to be the primary force of evolution. 

Thus, most Hindus who answer in affirmative when asked if they believe in theory of evolution are actually quite comfortable with reincarnation of karma-bearing soul as the cause of evolution of species which supposedly takes place in cycles of growth and decline, each lasting for billions of years (Nanda, 2010). What immediately stands out about these theories is how deeply and fundamentally they contradict Darwin. 

Questions about our origin and the topic of  human evolution always  generate intense interest across the world. In fact, no topic in all of science is more contentious or polarizing than evolution; on the top of it,  media sources often only serve to magnify this polarization.   Challenges to accepting and understanding evolution are many, which include mistrust and denial of science, cognitive obstacles and misconceptions, language and terminology, and a religious worldview.  

 WORLD VIEW

A perusal of  overall world view indicates that  evolution denial by much of the general public has been in stark contrast to consensus within the scientific community, despite nearly a century of increases in levels of formal education and scientific evidence.  As shown by various authors, it  ranges from “ignorance of the evidence to outright denial or distortion of data” (Liu, 2012, referred to in Pobiner, 2016), and stems from a myriad of often interwoven reasons. 

One of the most common questions and misconceptions is often  phrased as the question “if humans evolved from apes [or monkeys], why are there still apes [or monkeys]?” Or, why haven't all primates evolved into humans? Isn't evolution just an inference?  Why do not we see humans evolving from apes now? etc., etc. 

Pobiner (2016) refers to a study on 12th-grade Singaporean students’ understanding of human evolution using an open-ended question about human ancestry.  This study was done with students from a wide variety of religious background.  Most students thought that an extant ape gave rise to humans (like the minister!) . While  several students thought  that more than one species or a hybrid organism was the most recent common ancestor of humans and chimpanzees, some students inferred that since chimpanzees existed at 4 million years ago,  it must be them. 

According to Pobiner (2016), one  major reason for such misconceptions is the wrong perception  that evolution is always linear and innately progressive. Another reason may lie in  not clearly spelling out the issue of common ancestors versus living relatives. Pobiner opines that reiterating the  fact that we evolved from fossil apes (using the qualifier ‘fossil’ in front of apes) and that living species are neither ancestors nor descendants of each other might be helpful. Miekle and Scott (2010) also point out that the concept of “cousins” can be helpful in overcoming such  misconceptions.

 In light of the above, the minister’s statement is not surprising at all! In fact, he has brought to open the inherent belief and cultural  bias of majority of Indians with regard to human evolution, including that of the educated and enlightened ones. The minister himself is a PhD in Chemistry from a reputed university in India. This bias became further apparent to me when I tried to discuss the subject with my geologist colleagues, specialists of other disciplines,  and  even with my friends who are otherwise well accomplished. The discussions invariably lead to  some frequently asked questions (FAQs), like the one discussed above.

 As a working geologist I firmly believe that everything, all plants, and animals including human beings, are parts of the Earth System. The evolution of this planet and its atmosphere gave rise to life, which shaped Earth's subsequent development; this in turn brought about further evolution and development of life.  In my understanding many aspects of evolution of plants and animals  are linked with and would result from the natural processes that happen, interact, and work on the earth and shape the environment that in turn affect all the living beings and non-living things.  Their origin and evolution are  a part of the earth's developmental process, and it cannot be viewed separately.

 Here, it is pertinent to mention that developments in geology during the twentieth century has contributed immensely to the human evolution studies. Geological data have helped in interpreting the age of fossils based on stratigraphy, and also in the reconstruction of the palaeoenvironment that contributed to  the evolution and migration of ancient humans. The ability to directly date the artifacts, geological deposits or the fossils by various dating techniques  brought a new insight into the understanding of human origin and evolution processes, leading to a major breakthrough in prehistoric archaeology and palaeoanthropology. 

 However, in spite of having such a conviction, in spite of being a professional geologist with a  postgraduate degree  in exploration geology and  an honours degree  in chemistry I realised that my knowledge in human evolution is practically zero. Though I am conversant with  the basic concepts of palaeontology, I never studied the various aspects of human origin and evolution. Obviously, I failed to answer satisfactorily any of the FAQs. 

 So, I decided to acquire   some basic understanding and nuances of the processes that have led to the evolution of human beings as we know today. Simultaneously while reading the published literature on the subject,  I also jotted down the salient points in the form of some comprehensive note sheets. These are now being offered for perusal of those who are interested in gaining some understanding how we, the modern humans, came to  being into what we are  today.  

It is also apparent that most of the books on human origin and evolution in India are in English language and the texts are of technical nature. There is hardly any book or publication that describes the basic  of human origin and evolution  in a popular fashion in vernacular languages for non-specialists. I think in order to make Darwin’s views on origin and evolution of species in general, and human evolution in particular, acceptable to all we need to have many publications in different Indian vernacular languages.

 I must mention here that my studies are confined to the literature (books, research articles, reports, news items, etc.)  that are available freely online; credits are always given to the relevant authors.  I have not carried out any field investigations related to human origin and evolution and  my own understanding and opinion are based on my experience of  working as a professional geologist for more than four decades in many countries. 

 I am inspired by Mr. Christopher Seddon, author of many interesting books, including Humans: from the beginning: From the first apes to the first cities, published by Glanville Publishers.
