The 1906 San Francisco earthquake is considered the event that marks the beginning of the modern era of seismology. This earthquake resulted in significant advancements in the study of earthquakes and the development of seismological instruments and techniques.
The layer of iridium that is found in the Earth's crust is associated with the Cretaceous-Paleogene (K-Pg) boundary, which marks the end of the Mesozoic Era and the beginning of the Cenozoic Era. This layer is often linked to the mass extinction event that led to the extinction of the dinosaurs.
The separation of sister chromatids marks the beginning of anaphase in mitosis or meiosis. During anaphase, the sister chromatids are pulled apart towards opposite poles of the cell by the spindle fibers.
This produces a zygote (the fertilized egg).
The Prime Meridian, located at 0 degrees longitude, marks the starting point for measuring longitudes.
Gastrulation marks the beginning of germ layer development in an embryo.
Gastrulation is first step towards germ layer development .
The calendar is intended to mark the number of years since the death of King Herod the Great. The Roman abbot Dionysus Exiguus devised the new Christian calendar in 533. He knew that it was impossible to say when Jesus was born, but he knew, or thought he knew, when Herod died. So, he chose to begin his Christian calendar on the year of Herod's death, and he based this on the reign of the Roman emperor Augustus. Unaware that Augustus only adopted that name four years after his reign began, going by his birth name of Octavius until then, Exiguus commenced his calendar just 4 years too late.
The initial event in development is fertilization, where a sperm cell fertilizes an egg cell to form a zygote. This marks the beginning of the development of a new organism.
16 September is celebrated as ozone day. It marks the beginning as Montreal Protocol.

true it is.
The book in the Bible that marks the beginning of the New Testament is the Gospel of Matthew.
The beginning of germ development in an embryo is marked by the formation of primordial germ cells through a process called germ cell specification. These cells are the precursors to sperm and egg cells and are essential for sexual reproduction. Germ cell specification typically occurs during early embryonic development.
Fertilization is the fusion of a sperm and egg to form a zygote, while embryo development involves the growth and differentiation of cells in the zygote to form an embryo. Fertilization marks the beginning of development, while embryo development encompasses the processes that lead to the formation of a multicellular organism.
The fall of classicism, Huns, and Byaztine marks the beginning of the ppost classical period
The December solstice, which is the winter solstice in the northern hemisphere marks the beginning of northern winter.
