Twin development can occur at the cleavage stage if the developing embryo splits into two separate parts early in development. This can happen due to genetic factors or environmental influences. As the cells continue to divide and differentiate, each part of the embryo can develop into a separate individual, giving rise to monozygotic twins.
For Arnold Gesell, the term "Terrible Twos" referred to the stage in child development around age two where children typically exhibit increased assertiveness, independence, and defiance. Gesell viewed this stage as a natural part of development as children strive to assert their autonomy and navigate their growing sense of self.

Twin and adoption studies are common research designs that investigate the interaction between genetic and environmental factors in the development of psychological disorders. These studies compare rates of a disorder between identical and fraternal twins, or between biological and adopted children, to help determine the relative contributions of genetic and environmental influences.
Some people criticize twin studies because they assume that twins growing up in the same environment experience similar influences, which might not always be the case. Additionally, critics argue that twin studies may not account for genetic differences within twin pairs or the potential effects of epigenetics. Lastly, some critics suggest that the results of twin studies can be influenced by researcher bias or methodological limitations.
Yes, if one identical twin is diagnosed with schizophrenia, the other twin has a higher risk of developing the disorder compared to the general population. However, it is not a certainty and other factors such as environmental influences also play a role in the development of schizophrenia.

Aphex Twin is the stage name for British electronic musician and composer, Richard David James. His name is derived from the combination of Aphex (a reference to the brand "Aphex Systems Limited") and the word Twin in memory of his stillborn twin brother.
Whether the dam was a twin herself may have a little influence on her odds of giving birth to twins. Normally twins occur in one out of 1000 births.
Twin pianos have been set up on the stage so as to facilitate an amusing "duelling pianos" duet.
