Who was the scientist that first established the theory of evolution?
The answer is in the category this question has been entered into. Charles Darwin.Answer:Darwin proposed that species changed in response to natural processes. He knew that species could be modified by human intervention as the breeding of cattle, dogs, cats and various farm crops was widely practiced.Jean-Baptiste Lamarck proposed his theory of the transmutation of species, the first fully science bases theory of evolution. Both Darwin and A. R. Wallace published books on the theory of evolution in the 19th century.All early thinking on evolution including Darwin's, was hampered by the absence of any understanding or awareness of genes or DNA as messengers of change. As consequence many "Theories of Evolution" going back to the Greeks and Chinese were hampered by this lack.
What was the major weakness in Charles Darwin's theory during his life time?
One major weakness of Charles Darwin's theory during his lifetime was the lack of understanding of the mechanism of heredity. Darwin did not have access to the concept of genetics and could not explain how traits were passed down from one generation to the next. This gap in knowledge led to some skepticism and criticism of his theory of evolution by natural selection.
What two things did Darwin lack knowledge of?
Darwin lacked knowledge of genetics and the mechanism of inheritance, as well as the concept of DNA. These were not understood during his time and were discovered later, providing a more comprehensive understanding of how traits are passed down through generations.
The theory of use and disuse?
The theory of use and disuse of Jean-Baptiste Lamarck, advocated the idea that animals acquired characteristics after using certain physical traits constantly. For example, he believed that the reason why the necks of giraffes were long was because they stretched to reach leaves on high trees. By the same logic, the lack of a human tail could be explained by the fact that humans did not use it. This idea is not correct, however, it advanced evolutionary theory!
Which cells lack a nucleus?
Red blood cells lack a nucleus.
Why cannot you use the minerals of Antarctica presently?
The lack of suitable technology has hampered the mineral exploration of Antarctica.
Can you give me a sentence using acceptance associated with family?
My families lack of acceptance is a loathsome bother.
What does a child symbolize?
Innocence Wonder Acceptance Lack of guile
Lack of resources often leads to what defense mechanism?
Denial.
What elements initially hampered the advance of King Adolphus in northern Germany?
When King Gustavus Adolphus of Sweden landed in Germany in 1630, he led an army of approximately 13,000 troops. He was initially hampered by his lack of cavalry and his insistence that he created a firm base of operations before advancing.
What is the evidence against continental drift?
Some scientists initially doubted the theory of continental drift due to a lack of plausible mechanism to explain how continents could move. Additionally, the scientific community was initially resistant to the idea proposed by Alfred Wegener, as it challenged existing geological paradigms. It wasn't until the development of plate tectonics in the 1960s that continental drift gained widespread acceptance in the scientific community.
What doesan unconscious involuntary lack of acknowledgement of something is the defense mechanism known as?
Denial.
Why was Aristarchus's model of the heliocentric system not accepted?
Aristarchus's heliocentric model was not accepted in ancient times because it challenged the prevailing geocentric view that Earth was at the center of the universe. The lack of evidence and the influence of established beliefs hindered the acceptance of his revolutionary idea.
What keeps earth the same size?
The lack of any physical mechanism to change its size significantly.
Lack of money is not an obstacle lack of an idea is an obstacle?
Money is not the problem. Developing ideas is the issue.
What was one of the main objections to Wegner's continental drift hypothesis?
One main objection to Wegner's continental drift hypothesis was the lack of a plausible mechanism to explain how continents could move through solid oceanic crust. At that time, the idea of continental drift contradicted prevailing scientific beliefs about the rigidity of the Earth's crust.
Why did it take another 50 years for the continental drift to be accepted?
The idea of continental drift faced resistance due to lack of a plausible mechanism explaining how continents could move. It wasn't until the development of plate tectonics theory in the 1960s that provided a solid explanation for how continents move, leading to widespread acceptance. Additionally, scientific paradigms can take time to shift as new evidence accumulates and consensus builds within the scientific community.
