The evidence can only point to similarities berween "kinds" if the "kinds" are identified in the first place. It is better to say that the morphological evidence finds no evidence of distinct "kinds" at all.
Looking at chimps the hands, feet, skeletal structure, and internal organs are not that far from human. While not fully bipedal chimps are half-way there. While their intelligence is well below that of an adult human it is well above that of most other animals. Add in the fossil hominids and no, there is no clear division between between some nebulous "ape" kind and humans.
The "common design" explanation fails to explain much of the evidence - notably the overall pattern of similarities and also the genetic evidence.
And I still bet that a spider expert could find bigger morphological differences between spider species than between humans and chimps. The ability to build a web is a big one - some spiders do, others don't.
