|---|---|---|---|---|---|
| show | A special body part or behavior that helps a living thing survive in an environment.
🗑
|
||||
| show | It is when one species rapidly gives rise to many new species.
🗑
|
||||
| show | Body structures that are functionally similar in different species, but evolved independently. An example would be a bird's wings and a fly's wings.
🗑
|
||||
| show | A diagram that shows relationships between species.
🗑
|
||||
| show | Two organisms look in a very similar way, even though they are not closely related.
🗑
|
||||
| show | It is the change in populations of organisms over time--not change in the individual organisms, but change in the population of organisms.
🗑
|
||||
| extinct | show 🗑
|
||||
| show | a unit of inheritance; it is the directions for making a protein
🗑
|
||||
| show | These are similar physical features in organisms that share a common ancestor, but the features serve completely different functions. An example would be human arms (grasping objects), cat legs (walking), whale fins (swimming) and bat wings (flying).
🗑

| mutation | show 🗑
|
||||
| natural selection | show 🗑
|
||||
| phylogenetic tree | show 🗑
|
||||
| sexual selection | show 🗑
|
||||
| show | It is how a new kind of plant or animal species is created; it occurs when a group within a species separates from other members of its species and develops its own unique characteristics.
🗑
|
||||
| show | A group of similar organisms that are able to reproduce.
🗑
|
||||
| show | A physical characteristic, like your hair or eye color.
🗑
|
||||
| show | Body structures that have no apparent function and appear to be residual parts from a past ancestor.
