The two main types of monerans are bacteria and archaea. Bacteria are unicellular prokaryotic organisms found in various environments, while archaea are similar to bacteria but have distinct genetic and biochemical characteristics.
Lamarck Posited the concept of acquired characteristics being heritable and the organisms " need " to adapt physiological parts, such as giraffes " needing " longer necks. Needless to say both of these main concepts of Lamarck's were wrong. Darwin posited the theory of evolution by natural selection that saw selected variations of organisms evolving over time by their progeny inheriting favorable characteristics. Darwin had the evidence that Lamarck did not and his theory, with modifications, is still the best explanation of evolution and the origin of species extant.
There are three main types of pharmacopeia, which is the modern pharmaceutical recipes for creating narcotics, and they are city, national, and international pharmacopoeia.
Tiktaalik's fin bones were not connected to its main skeleton, and so could not have supported its weight out of water. And the similarity between species could also reflect common design. Answer Isn't the modern mudskipper evidence enough? Answer No. Recent discovery of the prints of a four-footed animal that dates in evolutionary terms at 18 million years earlier than Tiktaalik have forced scientists to reconsider their earlier assumption that Tiktaalik represented a missing link. Answer Tiktaalik serves as simply another transitional form linking the evolution between two groups of animals, akin to Archaeopteryx. It has become landmark but more work remains to be done. As new fossils are uncovered Tiktaalik will be likely be moved around the evolutionary tree.
The two main types of reptiles that existed in the Mesozoic Era were dinosaurs and pterosaurs. Dinosaurs were land-dwelling reptiles that roamed the Earth, while pterosaurs were flying reptiles that ruled the skies.
The function of the scientific process, also called the scientific method, is to answer questions based on experimentation and evidence.
quantitative and qualitative
His two main concepts, acquired characteristics and a innate " desire " to evolve, were both unsupported by any evidence and were not the way evolution happens. So, Lamarck's " theory " ( in the vulgar sense ) was utterly refuted by the actual evidence and process of evolution.
The main similarity between scientific theories and scientific laws is that both are supported by extensive evidence and are used to explain natural phenomena. However, theories are broader explanations that can be modified or refined based on new evidence, while laws are specific statements that describe a consistent pattern observed in nature.
Evolution is a fact-based scientific theory backed up by more than a century of research and observation. It is a solid theory that fits the facts observed in biology, paleontology, and geology. Evolution adresses the origin and evolution of life, not that of the universe. ID is a religion-based concept with no substantiated evidence that science would accept as such. It is in conflict with observed facts in four main scientific disciplines: biology, geology, paleontology, and cosmology. It makes statements about everything from the origin of the universe & the earth to the origin of life and denies the evolution of species, claiming that all species were created, but offers no explanation on the mechanisms of the process other than stating they are of supernatural origin.
There are multiple theories of evolution, but two main perspectives are the theory of microevolution focusing on small genetic changes within a population over time, and the theory of macroevolution which explains broader evolutionary changes leading to the emergence of new species. These perspectives are supported by various evidence from genetics, paleontology, and other scientific disciplines.
geologists use 2 main types of evidence
For a scientific report, the mian question is: How? For an author, the main questions are: Where and Who?
Personal beliefs and opinions are not a kind of evidence used to support evolutionary theory. Scientific evidence such as fossil records, DNA analysis, and observational data are the main sources of evidence.
Reduce bias and error in their research!
The four main sources of evidence Darwin used to explain evolution are fossil records showing transitions in species over time, homologous structures in different species suggesting a common ancestor, the geographical distribution of species supporting the idea of adaptation to local environments, and the observable process of artificial selection in domesticated organisms.
The three main pieces of evidence for the theory of evolution by natural selection are the fossil record showing transitional forms, comparative anatomy and embryology demonstrating similarities between different species, and molecular biology revealing genetic similarities indicating common ancestry.
