So if Lockheed or whatever his name was was partnered with Hammond but split as a result of Lockheed's decision to clone his daughter...thus explaining why we don't see Lockheed in Jurassic Park with Hammond in 1993... 25 years ago... why is his cloned daughter about 8 years old?share
It probably took several years to adapt the technology to use on humans.
shareThis movie implies they've been doing the cloning for quite some time before they moved operations to Isla Nublar. And of course, on Nublar, they already had a huge collection of finished dinosaurs. I don't think they come out of the tube as adults, so they must have been cloning them already several years before moving to the island in 1993. Based on some timeline sites I checked, they cloned the first living dinosaur in 1984. But the same sites reference her cloning to have happened in 2009, making the clone 9 year old in Fallen Kingdom.
So, to piece it together:
She was probably originally born about 1989 and died sometime around 1998. Her DNA was used to clone her in 2009 and her clone would be the aforementioned 9 years old in this movie. The picture in the movie shows a ~20 years younger Iris with a 9 year old Maisie, so probably around 1998, hence being born in 1989.
