Evolutionary Embryology

Embryology, the study of embryos, is an important cornerstone of biological evolution and can be used to help determine similarities and differences between various species. An embryo of an organism is the fertilized egg as it goes through the processes of development that is specific to that species. When looking at how the animal develops from an embryo to an adult, you can compare the …

Introduction to Embryology

Human development is a continuous process that begins when an oocyte (ovum) from a female is fertilized by a sperm (spermatozoon) from a male. Cell division, cell migration, programmed cell death (apoptosis), differentiation, growth, and cell rearrangement transform the fertilized oocyte, a highly specialized, totipotent cell, a zygote, into a multicellular human being. Most changes occur during the embryonic and …
