Darwin, Wallace, and the overlooked third man
2015-04-20
(Press-News.org) The horticulturist who came up with the concept of 'evolution by natural selection' 27 years before Charles Darwin did should be more widely acknowledged for his contribution, states a new paper by a King's College London geneticist.
The paper, published in the Biological Journal of the Linnean Society, argues that Patrick Matthew deserves to be considered alongside Charles Darwin and Alfred Russel Wallace as one of the three originators of the idea of large-scale evolution by natural selection.
Furthermore, Matthew's version of evolution by natural section captures a valuable aspect of the theory that isn't so clear in Darwin's version - namely, that natural selection is a deductive certainty more akin to a 'law' than a hypothesis or theory to be tested.
Patrick Matthew (1790-1874) was a Scottish landowner with a keen interest in politics and agronomy. He established extensive orchards of apples and pears on his estate at Gourdie Hill, Perthshire, and became adept in horticulture, silviculture and agriculture.
Whilst Darwin and Wallace's 1858 paper to the Linnean Society, On the Origin of Species, secured their place in the history books, Matthews had set out similar ideas 27 years earlier in his book On Naval Timber and Arboriculture. The book, published in 1831, addressed best practices for the cultivation of trees for shipbuilding, but also expanded on his concept of natural selection.
"There is a law universal in nature, tending to render every reproductive being the best possibly suited to its condition that its kind, or that organized matter, is susceptible of, which appears intended to model the physical and mental or instinctive powers, to their highest perfection, and to continue them so. This law sustains the lion in his strength, the hare in her swiftness, and the fox in his wiles." (Matthew, 1831: 364)
In 1860, Matthew wrote to point out the parallels with his prior work, several months after the publication of On the origin of species. Darwin publically wrote in 1860 "I freely acknowledge that Mr. Matthew has anticipated by many years the explanation which I have offered of the origin of species", while Wallace wrote publically in 1879 of "how fully and clearly Mr. Matthew apprehended the theory of natural selection, as well as the existence of more obscure laws of evolution, many years in advance of Mr. Darwin and myself", and further declared Matthew to be "one of the most original thinkers of the first half of the 19th century". However, both asserted their formulations were independent of Matthew's.
Even if Matthew did not influence Darwin and Wallace, his writings provide a valuable third point of reference on the notion of macroevolution by natural selection, argues the paper's author, Dr Michael Weale. Dr Weale has created a public website to act as an online repository of the writings by Patrick Matthew, including some of his lesser-known work.
Dr Michael Weale, from the Department of Medical and Molecular Genetics at King's College London, said: 'Whilst Darwin and Wallace both deserve recognition for their work, Matthew, the outsider who deduced his idea as part of a grand scheme of a purposeful universe, is the overlooked third man in the story. Matthew's story is an object lesson in the perils of low-impact publishing. Despite its brevity, and to some extent because of it, Matthew's work merits our renewed attention.'

Human emotion can be transferred by technology that stimulates different parts of the hand without making physical contact with your body, a University of Sussex-led study has shown.
Sussex scientist Dr Marianna Obrist, Lecturer at the Department of Informatics, has pinpointed how next-generation technologies can stimulate different areas of the hand to convey feelings of, for example, happiness, sadness, excitement or fear.
For example, short, sharp bursts of air to the area around the thumb, index finger and middle part of the palm generate excitement, whereas sad ...

Philadelphia, PA, April 20, 2015 - The search for genes that contribute to the risk for autism has made tremendous strides over the past 3 years. As this field has advanced, investigators have wondered whether the diversity of clinical features across patients with autism reflects heterogeneous sources of genetic risk.
If so, it was reasoned, then selecting a group of patients with very similar clinical features might result in a "purer", i.e., more genetically homogenous, group of patients, making it easier to find autism-related genes.

Research has shown that, for a number of reasons, lesbian, gay, bisexual and transgender people are significantly more likely than heterosexuals to avoid or delay medical care.
For instance, LGBT individuals who are between the ages of 18 and 44 and single are less likely than heterosexuals to have the money or insurance for care, and even partnered gays and lesbians are twice as likely to be uninsured. The fear of stigma and homophobia can also keep LGBT people from seeking care. And many are afraid to disclose their sexual or gender identity to their physicians, which ...

PHILADELPHIA - A protein produced by nerve cells appears to be elevated in the blood of those with an aggressive form of neuroblastoma. The finding, presented today at the American Association for Cancer Research 2015 Annual Meeting in Philadelphia, could potentially lead to a prognostic test for the disease or be used to monitor its progress.
Neuroblastoma is a pediatric cancer with varying types, ranging from spontaneously regressing to untreatable fatal tumors. Consequently, treatment strategies vary significantly between patients, encompassing different approaches ...

A decrease in the amount of time spent eating and an increase in overnight fasting reduces glucose levels and may reduce the risk of breast cancer among women, report University of California, San Diego School of Medicine researchers in the journal Cancer Epidemiology, Biomarkers & Prevention.
The findings were presented at the American Association of Cancer Research's annual meeting in Philadelphia.
"Increasing the duration of overnight fasting could be a novel strategy to reduce the risk of developing breast cancer," said Catherine Marinac, UC San Diego doctoral candidate ...

Early data in a preliminary human study show that an experimental immune system drug is generally safe and well tolerated in women with metastatic, triple-negative breast cancer, a persistently difficult form of the disease to treat.
Results of the early-phase clinical trial of the therapy, called MPDL3280A, which aims to restore the immune system's ability to recognize and attack cancer cells, are expected to be presented at the American Association for Cancer Research's 2015 Annual Meeting in Philadelphia from April 18-22. Triple-negative breast cancer cells lack expression ...

TORONTO, April 20, 2015--Although ultrasound remains the primary imaging modality used in prenatal imaging, fetal MRI is playing an increasing role in further evaluation of fetuses suspected of congenital anomalies. As 3-T MRI scanners become more common due to their improved image signal-to-noise ratio and anatomical detail, the benefits of 3-T MRI must be weighed against potential risks to the fetus that may result from the higher field strength.
"MRI is playing an increasingly important role in the assessment of complex prenatal disease," said Kathleen E. Carey, MD, ...

TORONTO, April 20, 2015--The design of inferior vena cava (IVC) filters for pulmonary embolism prophylaxis, once used almost exclusively for permanent implantation, has progressed to retrievable designs. However, complications can create scenarios in which the routine filter retrieval is either extremely difficult or impossible.
The use of advanced retrieval techniques, such as loop-snare, "sandwich," stiff wire or balloon realignment, forceps retrieval and excimer laser sheath can raise the overall success rate above 98%.
"Implementation of IVC filters is increasing ...

TORONTO, April 20, 2015--Research comparing the accuracy of three MDCT slice thicknesses has found that 3-mm slices underestimated coronary artery calcium (CAC) scores at every level of calcification. The inaccuracies were caused by partial volume averaging errors.
"Our analysis proved this concept and showed that CAC can be more accurately measured with 0.5 or 1 mm using isotropic data acquisition obtained by a volume scanner at identical radiation dose ," said Farhood Saremi, MD, University of Southern California. "Coronary artery calcium can be more accurately measured ...

TORONTO, April 20, 2015--Research conducted at the State University of New York Upstate Medical University has found that multiparametric MRI and subsequent fusion of MR images with ultrasound enables a targeted biopsy of high-suspicion foci with increased diagnostic accuracy of prostate cancer over established methods.
For patients on active surveillance for low-risk cancer, multiparametric MRI can better characterize the prostate gland and find occult foci of higher grade disease.
"The need to differentiate a clinically significant cancer from indolent cancers is ...
