You'd think that someone on CNN would be kinda smart (stop laughing)...
Cohen: "These are four-day old embryos. We’re talking about very tiny, tiny embryos."
Costello: "And they’re not fertilized either, right?"
Cohen: "Well no, an embryo is fertilized."
Costello: "Just to make it clear–"
Cohen: "Its sperm and egg have met each other–"
Costello: "So, it is?"
Cohen: "–and they, they’ve grown for about four days. So, they’ve formed a very, very small embryo."
Costello: "Ok, so I feel silly now."
If you have parts - know what they do. Please.
