Alfred Wegener had two flaws with his initial hypothesis. They are as follows:
i) Gravitational forces of the moon and sun, and tidal forces act as the mechanism to move the continents across the globe.
ii) Larger and sturdier continents broke through thinner oceanic crust like boat cutting through a thin layer of sea ice.
<u>Explanation</u>:
Alfred Lothar Wegener was a great meteorologist and German polar researcher. He was commonly known for his <u>“theory of continental drift”.
</u>
In this theory, they proposed an idea that the continents were slowly drifting around the Earth. Many researchers objected his view. But he provided many evidence to support his continental drift hypothesis.
Some of the evidences are: Continental jigsaw puzzle, Fossils match across the seas, Rock types and geologic features and Ancient Climates.
the differences between the Genain sisters in their experience of schizophrenia is de novo mutations in the fertilized egg or germ cells.
<h3>What is de novo mutations?</h3>
De novo mutations provide a mechanism for the persistence of early-onset reproductively lethal diseases in the population. These mutations, while individually rare, may account for a significant portion of the heritability for complex genetic diseases that genome-wide association studies cannot detect.
<h3>How do de novo mutations happen?</h3>
A genetic change that appears for the first time in one family member as a result of a variant (or mutation) in one of the parents' germ cells (egg or sperm), or a variant that arises in the fertilized egg itself during early embryogenesis. Also known as a de novo variant, new mutation, or new variant.
<h3>How many de novo mutations does a person have?</h3>
According to the findings, each person has approximately 70 de novo mutations that were not present in their parents' genetic code. Sasani et al. discovered that sperm and egg cells from older parents have more de novo mutations. This effect, however, varied significantly across Utah families.
