Biomimicking:

Artists have been inspired by nature for a long time now, whereas researchers have started appreciating the design of nature very recently. Most living things have perfected themselves over centuries of natural selection and survival of the fittest, where else could we find good design? Biomimicking is a new field where Scientists study designs of living things like insects, jellyfish, and gecko. They use these research on creating devices that would help us in different areas. See the following videos for more information.

Grafting:

Grafting is a process where tissues of plants can be joined to grow together. The possibilities are endless, one can graft an apple branch to a mango tree so that the mango tree can also produce apples. Grafting can be performed with multiple branches of different types of trees all on one tree.

Please see the following video where they have developed (through grafting) one tree which can grow 40 varieties of fruits.
