Grammar Focus: Word -Recognition
Humans have been blamed for the animal’s extinction, especially after a bounty program was instituted in Tasmania to protect sheep and other animals.
But in 2017, Andrew Pask, a biosciences professor, led research that found the thylacine also suffered from a lack of genetic diversity.
Reading Comprehension Fill-ins
The thylacine had trademark stripes and, rare in the animal world, abdominal pouches in both females and males. Australian researchers have called it ‘a dingo with a pouch or ‘a dog with a pouch’ — but its DNA also has a lot in common with the kangaroo.
Colossal, which has previously aired plans to resurrect the woolly mammoth, is intent on giving the thylacine ‘a second chance at life.’
