Represent the dialog for retrieving similar scenarios Speaker3: I've just read this interesting article about babies
Speaker1: hahah, why interesting?
Speaker3: Did you know that every year there are more male than female babies born?
Speaker2: Sure, it's normal, a phenomenon known for centuries
Speaker3: really? I haven't known
Speaker3: so what is the reason for that?
Speaker2: It's hard to say, there are different theories
Speaker2: what does the article say?
Speaker3: that the main theory is evolutionary
Speaker2: right
Speaker3: that boys and men generally die more often, so the nature regulates it to keep a balance between adult male and female
Speaker2: true, but some other scientists say it's about sperm
Speaker3: sperm?
Speaker2: yes, that female sperms (with chromosome X) are robuster 
Speaker2: but one doesn't exclude the other
Speaker3: It's fascinating
Speaker1: You're such a nerd really
Speaker3: hahah, a bit
Speaker2: Speaker1, we all are nerds :P you're just a technology nerd and an ignorant in every other field
Speaker1: I'm afraid it may be true
