What later evidence disproved Lamarcks theory of acquired characteristics and supported Darwins theory?
Later evidence from genetics and molecular biology showed that acquired traits are not passed down through generations as proposed by Lamarck, as they do not alter the genetic material. On the other hand, Darwin's theory of natural selection was supported by the discovery of the mechanism of inheritance through genes and DNA, providing a more robust explanation for evolutionary change over time.
Was over production in a population included in Darwins theory of evolution?
no the theory of evolution is a species becoming more advanced not over populated
Why is Darwins theory more than just a guess?
Darwin's theory of evolution by natural selection is supported by a vast amount of evidence from various scientific fields, including genetics, paleontology, and biogeography. It has been tested and confirmed through numerous observations and experiments, making it a well-established scientific theory rather than just a guess.
How did artificial selection influence Darwins theory of natural selection?
Artificial selection demonstrated that desirable traits could be purposefully selected and passed down in domesticated plants and animals. This helped Darwin understand that similar processes could occur in nature through natural selection, where organisms with advantageous traits are more likely to survive and reproduce. This supported his theory of evolution by natural selection.
When a hypothesis is supported by many different experiments it is considered a?
The explanation supported by many experiments is called scientific theory.
Is a hypothesis less supported than a theory?
Yes, a hypothesis is a proposed explanation that has not been extensively tested or confirmed, while a theory is a well-supported explanation that has been validated through repeated testing and observation. In scientific terms, a theory is considered more established and supported than a hypothesis.
What is the current theory of evolution?
That is a very hard question to answer as the "Theory of Evolution" is really an umbrella term for several theories based on the fact that allele frequencies of populations change over time, and the assumption that they have done so for the entirety of life on earth, as well as continuing on into the future. Evolution does NOT claim that there is no God. It makes NO STATEMENT whatsoever about spiritual matters. In fact, statistically speaking, the majority of the people who accept evolution are christians. It also does NOT include big-bang cosmology, does not require a multi-billion year-old earth, and does NOT address the origin of life at all, only its' variety. Current evolutionary theory can be traced to the moment when Darwin proposed his theory on the mechanics of evolution which overturned the previously held view proposed by LaMarck. LaMarcks theory of evolution proposed that an animal gains a trait in its' lifetime and then passes it on. Darwins theory replaced LaMarcks theory by proposing that changes were inherited, but not acquired during the lifetime of the individual. He attributed these changes to random mutations present from birth. Darwin did not stop with a mechanism for these changes, he also divised the "theory of Natural Selection" as a mechanism to favor beneficial mutations. Later, he proposed his "theory of Common Descent" as an explanation of the current variety we see in life. This theory proposes that at some point in the distant past, all living things share a common ancestor. Darwins three ideas have been confirmed through genetics, phylogenics, taxonomy, and paleontology, as well as being supported by every branch of science which can address biology. Through more discoveries, other scientists have developed even more specific theories based on evolution such as, "punctuated equilibrium", "evo-devo", and even the "Out of Africa" theory of human origins. The more we understand about the history of life, the more theories will be developed, but they are all part of evolutionary theory.
Which is not one of darwins four main ideas of natural selection?
Abiogenesis, or more commonly known as the origin of life itself, is not part of Darwin's theory of evolution.
Is Lamarck or Darwins theory more credible?
Darwin's. Duh. Lamarck believed in evolution by acquired traits; i.e., if a blacksmith hammers all day, his arm becomes strong. By Lamarck's theory, the blacksmith's strength would be transferred to his offspring, but this is never observed.
What is an explanation supported by a reliable body of data?
An explanation supported by a reliable body of data refers to a conclusion or theory that is backed by extensive and credible evidence from various sources or studies. This data provides robust support for the explanation, making it more trustworthy and likely to be true.
What are the differences between Darwin's and lamarcks theory of evolution?
Larmark's theory was based on the idea that organisms inherited characteristics that they had acquired in life - so, if you have a scar your offspring will have scars. Darwin's theory assumed that offspring inherited characteristics from their parents, but they were more likely to survive to breed if there was advantage to those characteristics.
What is the scientific theory behind the use of the periscope?
The operation of the periscope requires nothing more than the simple geometry of reflection from a plane mirror ... a theory that is well supported by observation and experiment. Its use requires no scientific theory.
