The rules of embryonic development were established by developmental biologists Lewis Wolpert and Peter Lawrence in the 1970s. They proposed a set of rules known as the "French flag model" that explain how cells in the developing embryo become specified into different tissues based on positional information. These rules laid the foundation for our understanding of how a single cell transforms into a complex, multicellular organism.
The inheritance of an organism tells cells to differentiate during embryonic development.
The development at an early stage for humans is called embryonic development, for pets is called embryonic or fetal development, and for petunias is called seed germination and seedling development.
The process of embryonic tissue development where tissue layers form during animal development is called gastrulation. This process involves the rearrangement and differentiation of cells to create distinct layers that will give rise to different body structures and organs.
The gonads develop around the sixth week of embryonic development. Initially undifferentiated, they differentiate into either testes (male) or ovaries (female) depending on the presence or absence of certain genes.
Pre-embryonic development is associated with processes including fertilization, cleavage, and formation of the blastocyst. During this stage, the zygote undergoes division and differentiation to form the blastocyst that will later implant into the uterine wall for further development into an embryo.
The neural tube develops into the brain and spinal cord during embryonic development.

Compare embryonic growth and fetal development in single and multiple pregnancies, including the incidence of complications and infant mortality.

It is fertilized and then poops.
During the process of embryonic development, you start as a single cell called a zygote, which is formed when a sperm fertilizes an egg.
Embryonic development can provide evidence for evolution by showing similarities in early stages of development across different species. These shared characteristics suggest a common ancestry and evolutionary relationships between organisms. By studying embryonic development, scientists can trace evolutionary changes and genetic relationships between species.
