Homologous and Analogous Traits.

Homologous Traits.

1A.) A venus fly trap- a plant that lives in swampy parts of the southeastern part of the US and is known for snapping and trapping bugs and digesting them, and a pitcher plant, whose leaves have been modified as a 'pitcher' to catch insects to digest.

1B.) The leaves of these two plant species. In a venus fly trap, the 'jaw' is the leaves of the plant that is used to trap and digest insects because those insects have the nitrogen and phosphorous that the soil lacks in the parts of the states where they are found. In pitcher plants, which can be found in most parts of canada, use their 'leaves' to catch insects and sometimes even larger prey (even snakes!). 

1C.) The common ancestor between the two would be the Drosera, which is essentially a sticky fly paper that uses it's leaves to capture insects by having them fly into their leaves and 'sticking' the bugs to their leaves and digesting them from there. 

1D.) 

Analogous Traits.

1A.) Penguins and a a fish.

1B.) The fins in each species- penguins are land and water based mammals who use their flippers to walk and to swim when in water as well and look more like claws than fins. Penguin fins are webbed, which allows them to walk on land as well as swim fast in the waters. Fish are specifically water animals, and their fins were developed in a way to allow them to glide them through the waters more easily. Fish also have many variations of fins in their body- they have dorsal fins, pectoral fins, pelvic fins, etc. Each specific fin was evolved to fit the needs of the fish to safely swim and live in the water.

1C.) I could not find a common ancestor, being that penguins are mammals and fish are sea creatures.
