Answer 1

后面的空格显然是 in order of 的应用；
前面空格用 in an order 不用 in the order ，前者an order表示有限随意性的,后者the order 有所指的，相对具体的。

追问

什么意思哦？那为什么不能用in order呢 不是有put something in order嘛？

Answer 2

put them in an order according to the time when they appared

按照他们现世的时间挨次把他们摆列成序，同理可推上句用in an order

in order of 指“按。。。。。排列”例如：按重要性，大小等排列。in order of importance/size

Answer 3

按句意来的、
把下面的事件根据他们的发展顺序排列
put sth in an order 是这个意思
