early in the movie we have a discussion saying that
the animals can't breed in the wild due to them all
being female:
"John Hammond: [as they gather around a baby
dinosaur hatching from its egg] I've been present
for the birth of every little creature on this
island.
Dr. Ian Malcolm: Surely not the ones that are bred
in the wild?
Henry Wu: Actually they can't breed in the wild.
Population control is one of our security
precautions. There's no unauthorized breeding in
Jurassic Park.
Dr. Ian Malcolm: How do you know they can't breed?
Henry Wu: Well, because all the animals in Jurassic
Park are female. We've engineered them that way."
and later with three of the characters wandering in
the park we have
"Dr. Alan Grant: [finding egg shells] Oh my God. Do
you know what this is? This is a dinosaur egg. The
dinosaurs are breeding.
Tim: But Grandpa said all the dinosaurs were girls.
Dr. Alan Grant: Amphibian DNA.
Lex: What's that?
Dr. Alan Grant: Well, on the tour, the film said
they used frog DNA to fill in the gene sequence
gaps. They mutated the dinosaur genetic code and
blended it with that of a frog's. Now, some West
African frogs have been known to spontaneously
change sex from male to female in a single sex
environment. Malcolm was right. Look..."
So, yes, the movie anticipated the OP from the BBC.
