you must be talking about a vestigial structure. Like our vestigial "tail".

What does a branch point in a cladogram represent?
The branch point in a cladogram represents a specific ancestor that is separated into two or more species. For example a leopard and a house cat share a common ancestor. A similar example is that a wolf shares a common ancestor with the leopard's and house cat's ancestor but the wolf's ancestor lived longer than the leopard's and house cat's ancestor. Scientists use something called cladistics to determine the one common ancestor that multiple species have in common.
What is the difference between a homologous structure and a analogous structure?
Homologous structures are different forms of animal anatomy which have come from the some origin (a common ancestor), these can be extremely different in appearance and function. For example a bats wing, a seals flipper and a human arm all have common bone and muscle structures suggesting that they all derived from a common ancestor. Vestigial structures are parts of the anatomy which have lost their original function through the evolutionary process and no longer obtain a major functional role in that animals life. For example in human the appendix's original function was to break down cellulose in plant material, other vestigial functions in humans include the coccyx (tailbone) and ear muscles.
How does speciation take place?
several generations
What is an organism that is no longer living called?

What if your aunt and uncle are not together anymore does that mean his daughters cousin's are no longer our cousin's?
They were never really your cousins. You don't share a common ancestor.

The relationship between evolutionary time and the similarity of genes in two species?
the longer it has been since 2 species split from a common ancestor, the more time that has elapsed for different mutations to accumulate in each separate lineage.
What is decent with modification?
The process by which different species can be descended from a common ancestor. The idea is that as genes are passed from an organism to its children to its children's children, accidental modifications to the genes (errors in copying) can accumulate to such an extent that after many thousands of generations some of the descendants no longer resemble their ancestor of thousands of generations before.

What are the most common coding errors that occur in Cpp and what are the best ways to prevent them?
Using the assignment operator (=) instead of the equality operator (==) is one of the most common errors, one of the few that was inherited directly from C, and is unavoidable. Another common error is in not releasing resources when they are no longer required, but this can be avoided by using references instead of pointers as much as is possible.
Do we come from monkeies?
Yes. Turns out we did. The most recent common ancestor between monkeys and apes (such as ourselves) were also monkeys.What we DON'T come from is any monkey that is alive today. We share a common ancestor with them, which was a monkey too.Previous answer:No, we don't. If we did, then why are monkeys still around?That's not correct. We also descend from reptiles, and there are reptiles around. We descended from fish, and there are still fish around.Cladistically speaking, we're still apes, we're still monkeys, we're still primates, we're still mammals, reptiles, tetrapods, fish, etc.Monkeys and other animals we are related to all descended from a common ancestor millions of years ago. That common ancestor no longer lives.That's correct. But we still came from monkeys.
Do plants have inherited traits?
RNA, the pea pod thing. Longer or shorter, really not much for more advanced heavier chromosomed plants.
