When unrelated groups evolve similar traits because they face similar environmental pressures we call this what?
convergent evolution

What type of features were used to build phylogenetic trees? What do we use now?
morphological (physical) features, molecular

This process involves large-scale patterns: speciation, major transitions, and diversification across long time periods
macroevolution
500
This process involves going from 1 cell to 4 genetically unique cells.
Also list where this process occurs.
meiosis

This phylum includes animals that must molt to grow, have an exoskeleton, and jointed appendages
arthropoda

If only a few female sea turtles begin using a newly formed nesting beach, the future population may reflect only a small portion of the species' overall genetic diversity. (This is an example of what process)
The founder effect

Identify the group
paraphyletic

Northern Elephant Seals were hunted almost to extinction for their blubber, which was used in oil production. Nearly all genetic diversity within the species was lost, as the surviving individuals represented only a tiny fraction of the original gene pool. (This is an example of what process)
bottleneck effect
