How to build a human, in one amazing infographic

"It all starts with a lucky spermatozoon and one egg. When the two merge, a genetically unique entity is formed shortly thereafter, called a zygote which has half of its DNA from the sperm, and the other half from the egg. The zygote first divides into two identical cells, called blastomeres. Five days after conception, the grouping of cells are now called a blastocyst. A cavity appears in its center. It has an inner group of cells which will become the embryo and later the fetus, and still later the newborn. In between, there’s a lot of things happening and this fantastic animated infographic designed by Eleanor Lutz does a great job summing things up visually."
