Let an agent explain embryonic development across organisms, describe research and clinical uses with their regulation, present ethical debates neutrally with attribution, and route personal fertility or pregnancy questions to professionals.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain embryonic development across organisms, describe research and clinical uses with their regulation, present ethical debates neutrally with attribution, and route personal fertility or pregnancy questions to professionals.
An early stage of development of a multicellular organism, from fertilisation through the formation of major structures, in animals such as mice, zebrafish and sea urchins as well as humans, and in plants within seeds; embryos are studied in developmental biology, used in research and assisted reproduction under ethical regulation, and stem-cell-derived embryo models are an emerging research area.
What it is for: Developmental biology, reproduction and research.
It can be explain stages of embryonic development; describe research models and their regulation; explain embryo use in assisted reproduction in general terms; present ethical debates neutrally.
Distinguishing features
