This scenario teeters on the verge of B-movie science fiction, but still, let's say that some ambitious scientist, who is an avid fan of mythology, uses that childhood obsession to test genetic experiments on his fellow human. The list is as follows:

**Satyr**

A population of humans where 20% of their genetic makeup stems from *Capra sibirica*, the Siberian Ibex.

**Werecat**

A population of humans where 20% of their genetic makeup stems from *Panthera pardus*, the Leopard.

**Werewolf**

A population of humans where 20% of their genetic makeup stems from *Canis lupus*, the Grey Wolf.

**Selkie**

A population of humans where 20% of their genetic makeup stems from either *Zalophus californianus*, the California Sea Lion, or *Eumetopias jubatus*, Stellar's Sea Lion.

**Mer**

A population of humans where 20% of their genetic makeup stems from *Tursiops truncatus*, the Bottlenose Dolphin.

**Berserker**

A population of humans where 20% of their genetic makeup stems from either *Ursus maritimus*, the Polar Bear, or *Ursus arctos*, the Brown Bear.

Note that the one theme of this list is that the human genome has been altered by 20% to create these mythological hybrids. Is that percentage major enough for changes in physical exterior characteristics? Would behavior be affected?
