This is the second part of a post summarizing current understanding of the evolution of humans. In the previous post, I outlined the evolution of pre-human species from the first monkeys around 35 million years ago (Mya) to the appearance of the first human species around 2 Mya. This post takes a look across the evolution of humans from the appearance of the first human species Homo habilis to the appearance of anatomically modern Homo sapiens sapiens around 250 thousand years ago. The following figure summarizes the evolution of humans over the last 2 million years, based on  with some modifications to take account of some recent discoveries.
Our understanding of the evolution of us modern humans has changed dramatically in the last few years as ancient genomes are decoded and we discover that humans, Neanderthals and Denisovans interbred, and also in the remote past interbred with previously unknown “superarchaic” human groups. Scientists are also discovering new species of extinct hominids, and no doubt will continue to shed further light on our origins. Just to try to sort out the big picture in my own mind and to put these various discoveries in context, I’ve tried to summarize what we think we know, or at least what the evidence available to date suggests. This will no doubt continue to change.
This is the first of two posts and summarizes the evolution of pre-human species from the first monkeys around 35 million years ago (Mya) to the appearance of the first human species around 2 Mya. A following post will summarize the evolution of humans from the appearance of the first human species Homo habilis 2 Mya to the appearance of anatomically modern Homo sapiens sapiens around 250 thousand years ago and mitochondrial Eve, who lived around 178,000 years ago.
In an early post on this blog, I summarized my maternal-line ancestors and where and when they lived. In the last 6 years, there have been substantial revisions to estimates of the dates associated with these mitochondrial DNA (mtDNA) haplogroup founders, and revisions to the mtDNA haplogroup tree (deep-maternal-ancestry-and-mtdna) and this post provides an update. I am a member of mtDNA haplogroup U5, which is one of nine native European haplogroups stemming from haplogroup U which most likely arose in the Near East, and spread into Europe in a very early expansion. The presence of haplogroup U5 in Europe pre-dates the last ice age and the expansion of agriculture in Europe. Today, about 11% of modern Europeans are the direct maternal descendants of the founder U5 woman. They are particularly well represented in western Britain and Scandinavia. My more recent maternal ancestors were part of the population that tracked the retreat of ice sheets from Europe at the end of the last ice age and re-colonized Britain about 12,000 years ago.
The mtDNA sequence at the root of each haplogroup arose from one or more mutations in the mtDNA of just one woman, and the age of the associated haplogroup gives the time in the past when this specific woman lived. To emphasise that the maternal clan founders were real individuals, I have used the names given to them by Sykes  and Oppenheimer  and given my own names to the more recent subgroup founders. The Table below summarizes these founders, dates and locations and is followed by brief biographies. The haplogroups are identified by the labels used in Build 17 of the ISOGG mtDNA tree which can be accessed at http://phylotree.org/ . Dates in the table below have been updated using most recent available dating estimates as described in my previous post deep-maternal-ancestry-and-mtdna.
The migration path out of Africa into Europe of the “grandmothers” linking mitochondrial Eve through to Ursula (U5) is shown on a map in my previous post deep-maternal-ancestry-and-mtdna. The subsequent migration from Europe to Britain is shown in the map below.
Updated biographies of my maternal haplogroup great* grandmothers follow below.
In February 2014, I did a series of posts on my deep maternal ancestors, identified through a test of mutations on my mitochondrial DNA (mtDNA) which is inherited only from the mother. This test was carried out by Ancestry.com, who have since discontinued tests of mtDNA and Y-chromosome DNA. Costs of DNA tests have dropped dramatically since then, and late last year I ordered an mtDNA test from FamilyTreeDNA (www.familytreedna.com) which carried out a full sequencing of the mitochondrial DNA.
As well as the DNA that makes up the chromosomes in the nuclei of our cells, we also have another type of DNA called mitochondrial DNA (mtDNA). The mitochondria are organs located outside the cell nucleus which convert sugars into energy. Mitochondria have a small circular loop of DNA, containing only approximately 16,569 base pairs in humans. The circular mtDNA is similar to the DNA of bacteria, and it is thought that mitochondia evolved from symbiotic bacteria that were once free living.
Back in 2011, I discovered that one of my great-great- great-grandfathers (on grandpa Baker’s side) Thomas Wilson (1817-1890) had been transported to Australia in 1835 as a convict. He and two others had committed a highway robbery.
Just recently, I came across convict records that gave more information and a description of him. He was aged 21, single, a Protestant who could read and write. He came from Kent, and was a skinner and poulterer. According to the convict records, he was 5 feet 4¾ inches tall, with ruddy and freckled complexion, brown hair and grey eyes, his eyebrows partially meeting. Among various marks and scars, he had (presumably tattooed) a sun, half moon, seven stars and a crucifix inside his lower left arm. At this point, I realized I was out of my depth, and called in the renowned symbologist, Professor Robert Langdon of Harvard, who told me that the sun, moon and seven stars were a set of symbols used by Freemasons and were also adopted by the Order of Oddfellows, founded in the eighteenth century. The Oddfellows modelled themselves on freemasons though were dedicated more to people of modest lifestyle, labourers and artisans. For the Oddfellows, the “sun, moon and stars” collectively might represent all God’s creation, all that is wonderful and admirable. The seven stars recalls The Pleaides constellation representing the “seven liberal arts”, and for a skinner and poulterer would probably translate to literacy and numeracy.
Langdon concluded that a literate 19 year old working class boy who was already a member of the Oddfellows and had a distinctive set of symbols tattooed on his arm was unlikely to have been a simple highway robber. Could he have deliberately set out on a course of action that would result in him being transported to NSW? Was there any significance that after he was given his ticket of leave, he bought substantial land holdings in the Manly area in 1853? Land now worth $300 million. And in 1869 became tenants of the “Mona Vale” property belonging to William Charles Wentworth, one of the three explorers who found the first route across the Blue Mountains in 1813. Was it significant that when he arrived in Australia in 1835, Wilson was first sent to Paramatta to work for William Lawson one of the other three explorers. Could it be another coincidence that Thomas Wilson sold his land in 1877, exactly one year before the foundation stone was laid for the first Oddfellows Hall at Manly.
Langdon immediately flew to Geneva and interviewed Mathers, seeking any evidence of Oddfellows involvement in his life. Mathers was surprised at the turn this research had taken, and unwilling to believe that the location of the Oddfellows Hall in Casino just half a block from where he lived as a child was anything more than coincidence. Or that one of father’s close colleagues was the Warden of the local Oddfellows Lodge. And why did the Lodge reach out and offer Mathers a scholarship as a teenager that enabled him to visit New Zealand. Why did they try to bend his interest in astronomy towards astrology and more occult concerns? Clearly Langdon would have to follow the leads in New Zealand to see what connections were found.
Discussions with Mathers also revealed that in the 1940s, his grandfather had applied considerable pressure on his mother to get her to visit two elderly women in Mosman, the granddaughers of Thomas Wilson. Why was it so important that this contact be made? Could the Oddfellows really have had a plan, a vision, reaching centuries ahead. And what could it possibly be?
In a recent post, I described the descent of my great-aunt Boodie (Florence Teasdale Smith) from an Indian Princess. Princess Budhson (was the daughter of Raja Shahu II Bhonsle (1763 – 3 May 1808), who was the titular Chhatrapati (emperor) of the Maratha Empire, and his third wife Rani Shrimant Akhand S Gunwatabai.
The Ancestry database India, Select Births and Baptisms, 1786-1947 (1) contains an index entry for the marriage of Henry Crawshay Teasdale to “Native Woman Buh’Hson”. The same name is cited on the birth certificate for her daughter Emma. Her name is also variously given as Budhson or Bakshan in various sources and family trees. I did a google search for names in the district of Satara in the Maharashtra state in Western India and found “Bakshan” but no mention of the other two variants. So perhaps Bakshan was the currect version of her name.
Major Henry Crawshay Teasdale(1801-1843) and Princess Buh’Hson (1803-1831) had three children Ellen Teasdale (1825-1895), Emma Mary Teasdale (1825-) and Henry Jackson Teasdale (1830-1870). As Emma was born in May 1825, it is likely that she and Ellen (from whom my Aunty Boodie is descended) were twins.
