Compared to the majority of other species, humans have a lot of developing to do (both physically, and cognitively!) Foals stand up and begin to walk in the first hour. At birth, the human brain is only 25% the eventual adult weight. However, much of development is completed before we are born! At conception, the zygote is a single cell. then after 36 hrs 2 cell, then 3 cells at 48 hrs and so on. After 4-5 days you are a ball of cells with about 64 cells, then you get a progressive splitting and doubling of cells and then the cells specialize.
