Quotes About Mammalian

He seems to have developed a rare, little-understood affliction called poikilothermism. The victim loses the normal mammalian ability to keep his body temperature constant, regardless of changes in the ambient temperature. His body assumes the temperature of its surroundings, as if he were a reptile or a fish.

The genetic stage of a gene pool can be identified by the personality characteristics of the local God. Jehovah of Genesis is a low-level barbarian macho punk God. He boastfully claims to have created the heaven and the stars and the world, but provides no technical details or replicable blueprints. His preoccupations, whims, anxieties, jealousies, rules and hatred of women are primitive mammalian brain. His petty prides are primate.

In the 1950s, American psychology was dominated by the behaviorists, whose endless experiments with lab rats aimed to show how easily the mammalian mind was shaped by its environment. Harlow

Hunger and sex still dominate the primitive mammalian side of human existence, but at the present time it looks as if humanity were within sight of their satisfaction. Permanent plenty, no longer a Utopian dream, awaits the arrival of permanent peace.

A quite rare but nevertheless important event before gastrulation in mammalian embryos, including humans, is the splitting of the embryo into two, and identical twins can then develop. This shows the remarkable ability of the early embryo to regulate and develop normally when half the normal size, just like the Driesch experiment. It also makes clear that the early embryo should not be thought of as a human being as it can still develop into two people.

Neurons are formed in the proliferative zone of the vertebrate neural tube from multipotent neural stem cells, which give rise to many different types of neurons and to glia. For many years it was thought that no new neurons could be generated in the adult mammalian brain, but the production of new neurons has been demonstrated as a normal occurrence in the adult mammalian brain, and neural stem cells have been identified in adult mammals that can generate neurons.

The reason for men's higher mortality, like that of males of many mammalian species, stems directly from their sexual psychology, and in particular from their competition for mates. The use of risky tactics of competition becomes greater as the differences in reproductive outcome become greater.

La corteza cerebral es la capa más externa del cerebro. También se le llama neocórtex o «nuevo cerebro mamífero» porque experimentó un gran desarrollo con la aparición de los primates y, sobre todo, con la aparición del ser humano.

It was still diving, it was still letting go of mammalian pride and embracing gravity.

The first and most basic evolutionary point is that the primary targets and beneficiaries of sociality are the offspring. Why? Because mammalian babies are immature at birth and will certainly die without care. Baby turtles, after hatching from their eggs, immediately dig their way up out of the sand, scuttle down to the water, and begin to look for food. No parents are anywhere close by, nor are any needed.

That work led to the emergence of the recombinant DNA technology thereby providing a major tool for analyzing mammalian gene structure and function and formed the basis for me receiving the 1980 Nobel Prize in Chemistry.
