This suggested not only that species could change — already a divisive concept back then — but also that the changes were driven
purely by environmental factors, instead of divine intervention.
A shared upbringing accounted for only 36 per cent of the differences, with the remainder accounted
for by environmental factors that weren't shared, such as each twin having a different teacher.
This change creates risk factors for depression, anxiety and anger, all which can be
enhanced by environmental factors like unhealthy living conditions, violence or drug abuse in the home.
The genetic analysis is built on extensive international scientific findings showing that up to 60 % of our personality is influenced by DNA, with the rest being
affected by environmental factors.
One difficulty in studying the genetics of common mental illnesses is that they are generally caused
by environmental factors in combination with multiple gene variants, any one of which usually could not by itself cause disease.
Although genes contribute to the array of abilities and limits each of us possesses, from conception forward their expression is constantly
shaped by environmental factors, by the unique experiences of each individual and by purely chance factors in biological and social development.
CANCER is often caused
by environmental factors including toxic chemicals added to household goods, pesticides and poor air quality, local Green Party MEP Caroline Lucas will tell a Brighton cancer - prevention day this Saturday, February 9th.
The degree of hereditability is moderate in nature, meaning that the formation of the hip joints can also be
modified by environmental factors such as over nutrition, excessively rapid growth, and certain traumas during the growth period of the skeleton.
Additionally, countless mothers without such medical conditions may be
limited by environmental factors, such as difficulty with latch, poor breastfeeding education, or a lack of support from their employer or significant other.
«The brain along with the reproductive system and every other cell in your body is exquisitely sensitive to exceedingly small changes in estrogen and other sex hormones, and the fact that the environment is full of chemicals that can activate estrogen receptors means this phenomenally sensitive system is being perturbed
constantly by environmental factors.»
The speaker in the cartoon is assuming that if homsexuals are made
so by environmental factors, then all humans must be born neutral and their sexuality, in either direction, is shaped by the environment; when in fact one could also argue (and I believe the argument actually is) that humans are born hetero by default and shifted to homosexuality be environmental factors.
Natural tear production tends to decrease with age, dipping hormone levels can exacerbate dryness, and eyes may be more easily
irritated by environmental factors like dust, medications, and contact lenses, says John Huang, MD, an assistant professor in Yale Universitys department of ophthalmology.
However, risk and severity of hip dysplasia may also be
increased by environmental factors such as overfeeding that leads to rapid growth during early puppyhood, neutering prior to maturity, and possibly certain types of exercise.
It is a complex genetic trait (involving several genes) which can be made
worse by environmental factors such as a dog being overweight or having inappropriate exercise.
A dog can be dysplastic in one or both hips, can have a shallow socket and a normal ball, a malformed ball and normal socket, a shallow socket and malformed ball, a misaligned joint, loose ligaments, or a combination of these structural problems
complicated by environmental factors such as rate of growth, level of nutrition, and exercise.
Treating Dog Eye Allergies: These types of allergies are also
casued by environmental factors, insect bites near that eye, food allergens and hypersensitivity by the immune system.
The scale of human activity, the level of natural resource consumption (both because of increased human population and increased expectation of material comfort), is so much higher now, that China's economy, and that of other developing nations as well, could easily become constrained
by environmental factors before they can turn to cleaning up their environment, as happened elsewhere.
However, current understanding suggests that, unless substantial ocean circulation changes occur, plankton growth remains roughly unchanged because it is limited
mostly by environmental factors, such as nutrients and light, and not by the availability of inorganic carbon it does not contribute significantly to the ocean uptake of anthropogenic CO2.
