How is Jensen's theory related to Galton's early work?
Jensen's theory of intelligence proposes that individual differences in intelligence are largely due to genetic factors, whereas Galton's early work laid the foundation for research into the heritability of intelligence. Both theories focus on the role of genetics in shaping intelligence, with Jensen's theory building on Galton's ideas by incorporating more modern genetic research methods.
Who are some foreign and local scientists and their contributions?
Foreign scientists like Albert Einstein (theory of relativity) and Marie Curie (discovered radioactivity) made significant contributions to science. Locally, scientists like Elizabeth Blackburn (telomeres research) and Richard Feynman (quantum mechanics) have also made important contributions to their respective fields.
Charles Darwin was British, born in England in 1809. He is known for his contributions to the theory of evolution through natural selection.
What is the theory of Spontaneous Reproduction?
spontaneous reproduction is when out of no where, something is reproduced. many, many, years ago, people didn't have refrigerators to keep their food fresh. so their meat and other foods would spoil and so there would be magots and other insects crawling in their food. their explanation would be spontaneous reproduction.(they thought dead meat could reproduce living organisms)
the reason why people get upset is because other people be making them mad or someone getting on their last nerves or they just say things to make you mad.but listen for some good advice,don`t let people make you mad with words they say because words and talk don`t hurt anyone.because the reason they want to make you mad is so you can hit them first and get you into trouble.
This depends on what side you take, and what time period. Here's my view: when it started it was great, woman began to acquire rights, but now its gone a little far. They push for legislation to have more rights then men. I agree that men and woman need to be equal, but not one over the other. Also may i add, most feminists agree with me, we need to be equal, but others think women over men, but this is a small subset.
here is some proof: 2 woman attacked a cashier ( who was male ) a while back. he decided to back up because he didn't want to get into trouble. They actually hit him before their final attack. They then lunged over to try to assault him. He grabbed a spatula and fended them off. HE WAS ARRESTED AND CHARGED FOR ASSAULT, THEY HIT HIM FIRST. Thats the new theory, extra women rights. Once again their old theory was great.
Please don't erase my response. Just add onto it if you dissagree.
Darwin's Theory of Evolution is the widely held notion that all life is related and has descended from a common ancestor: the birds and the bananas, the fishes and the flowers -- all related. Darwin's general theory presumes the development of life from non-life and stresses a purely naturalistic (undirected) "descent with modification". That is, complex creatures evolve from more simplistic ancestors naturally over time. In a nutshell, as random genetic mutations occur within an organism's genetic code, the beneficial mutations are preserved because they aid survival -- a process known as "natural selection." These beneficial mutations are passed on to the next generation. Over time, beneficial mutations accumulate and the result is an entirely different organism (not just a variation of the original, but an entirely different creature).
What Theories are now rejected?
The evolutionary theory called the theory of acquired characteristics. The geocentric model. Spontaneous generation. Phrenology. The Ether (theorized medium for propagation of light). Aristotle's view of gravity. Newtonian mechanics (under relativistic conditions).
What is the naturalistic theory?
The naturalistic theory is a philosophical approach that explains phenomena based on natural causes and laws, without resorting to supernatural explanations. It assumes that the natural world can be understood and explained through scientific inquiry and observation. This perspective rejects the existence of gods, spirits, or any other supernatural entities as explanatory principles for phenomena in the world.
What is te difference between labeled line theory and acros fiber pattern theory?
labeled lines theory: Different qualities of a percept such as hot versus cold, sweet versus salty are encoded by separate group of cells. The information within a series of cells transmitting information to the brain remains within separate channels or lines.
Pattern theory.
Differences in the spatio-temporal pattern of electrical activity within a group of cells encode different qualities.
HI!!!...
"Most sensory receptors are maximally sensitive a single stimulus energy, a property sometimes termed receptor specificity. Specificity is a key property of receptors and underlies the most important coding mechanism for stimulus modality, the labeled line code. The axons of receptors function as modality-specific line of communication between the periphery and the central nervous system carrying information about a specific modality. Whether pain or touch is perceived depends on the central connections of the receptors (different types of receptors have different sets of connections in the central nervous system). Thus, excitation of a particular receptor, wether by a natural stimulus or artificially by direct electrical stimulation, always elicits the same sensation.
Not all sensory information is transmitted by labeled line codes. A relatively uncommitted receptor (or neural pathway) can signal different modalities by using different patterns of firing, called a pattern code. Certain types of chemoreceptors lack specificity to a single stimulus. It is thought that different modalities of chemical stimulation (for example, different aspects of taste) are elicited by different discharge patterns of chemoreceptors"

Why have scientists changed their theories about Venus?
Scientists have updated their theories about Venus because of new data collected from recent spacecraft missions. These new findings have revealed a better understanding of Venus's atmosphere, surface, and geological features, prompting a revision of previous assumptions.
What time and place did Darwin's theory occur?
Charles Darwin's theory of evolution, outlined in his book "On the Origin of Species," was published in 1859 in England during the Victorian era.
It is the reason humans and all of life on Earth exist. It is the most powerful idea ever to come into the human mind. Charles Darwin discovered the reason why we exist and in the process answered questions of the sort "What is the meaning of life?"
Why is evolution important in biology?
As far as scientific investigation has been able to determine, evolution is the means by which life as we know it has come about on our world. It is the fundamental process which underlies all of biology.

How long does chromatic adaptation take to occur?
Chromatic adaptation can happen rapidly within minutes in response to changes in lighting conditions. Full adaptation can take anywhere from 5 to 20 minutes, but it can vary depending on the individual's sensitivity to light and the magnitude of the lighting change.
What are two of the driving forces behind the process of natural selection?
Two driving forces behind natural selection are variation within a population, which creates diversity in traits, and differential reproductive success, where individuals with advantageous traits are more likely to survive and reproduce.
What is the Cosmozoic Theory of Evolution?
Cosmozoic or Interplanetary Theory as put forward by Richter states that life had reached the earth from some other heavenly body in the form of resistant spores of simple organisms in meteorites or in spaceships. Upon finding fertile soil here, the theory goes, they grew and then evolved into the various existing forms.
Why must an adaptation be inheritable if it is to cause a population to evolve?
An adaptation must be inheritable in order to be passed down from one generation to the next. If an adaptation is not inheritable, it will not be maintained in the population over time through natural selection, and therefore will not lead to evolution. Inheritability ensures that the adaptive trait can increase in frequency within a population over generations.
What is the cultural evolution of man?
I believe that before Darwin created his theory the culture was a Christian culture, most everyone believed in God, how God created the earth in seven days, and how everything has a plan and purpose. Once Darwin created his theory, everything changed. Everyone believed that there is no God, The earth was created by a Big Bang, everything in the earth was evolved from a single cell, everything happens accidentally, and nothing has a purpose you are just here because the best traits adapted and evolved. Evolution has completely taken the focus away from God, and put it on the fact that we don't need God to create life. Evolution is taking the culture and little by little, day by day, turning it into more of an Atheistic world view. That is not what God intended to happen!!!

Theory of evolution according to f landa jocano?
F. Landa Jocano, a Filipino anthropologist, proposed a theory of evolution that emphasized cultural evolution over biological evolution. He argued that cultures evolve through adaptation to their environment and social interactions, rather than through genetic changes. Jocano's theory highlights the role of cultural diversity and innovation in shaping human societies.
How variation developed and maintained in population?
Stabilizing selection for an intermediate optimum is generally considered to deplete genetic variation in quantitative traits. However, conflicting results from various types of models have been obtained. While classical analyses assuming a large number of independent additive loci with individually small effects indicated that no genetic variation is preserved under stabilizing selection, several analyses of two-locus models showed the contrary. We perform a complete analysis of a generalization of Wright's two-locus quadratic-optimum model and investigate numerically the ability of quadratic stabilizing selection to maintain genetic variation in additive quantitative traits controlled by up to five loci. A statistical approach is employed by choosing randomly 4000 parameter sets (allelic effects, recombination rates, and strength of selection) for a given number of loci. For each parameter set we iterate the recursion equations that describe the dynamics of gamete frequencies starting from 20 randomly chosen initial conditions until an equilibrium is reached, record the quantities of interest, and calculate their corresponding mean values. As the number of loci increases from two to five, the fraction of the genome expected to be polymorphic declines surprisingly rapidly, and the loci that are polymorphic increasingly are those with small effects on the trait. As a result, the genetic variance expected to be maintained under stabilizing selection decreases very rapidly with increased number of loci. The equilibrium structure expected under stabilizing selection on an additive trait differs markedly from that expected under selection with no constraints on genotypic fitness values. The expected genetic variance, the expected polymorphic fraction of the genome, as well as other quantities of interest, are only weakly dependent on the selection intensity and the level of recombination.
What is a theory designed to do?
A theory is designed to explain a phenomenon or set of phenomena based on observation, experimentation, and reasoning. It provides a framework for understanding how and why certain things happen in the world, helping researchers and scientists make predictions and test hypotheses. Ultimately, a theory aims to increase our understanding of the natural world and guide future research.
What is descent with modification?
Descent with modification encapsulates the two key ideas central to the theory of evolution. These are that modifications (mutations) occur, and that these mutations are inheritable (passed on to descendants or offspring).
