has created
With the help of small pieces of leaf, dead insects and other debris, a spider in the Amazon rainforest has created a detailed replica of a spider larger than itself.
The crafty spider is thought to be a new member of the genus Cyclosa, a family of spiders which has created decoys before using spare egg sacs. But this new spider's sculpture is the first to have leg-like appendages.

For what purpse, do the yellow blocks have the present perfect tense, not present?

In the first sentence, the present perfect indicates that the work is finished.
The simple present would probably be used as "historical present" to create a narrative, describing a work in progress: In the Amazon rainforest a spider creates a replica. This would be equal in meaning to "a spider is creating a replica."
The second sentence is quite a different thing.
