Macroevolution
A diagram that shows evolutionary relationships between organisms.
What is a phylogenetic tree?
Organisms that need to consume other living things to get energy.
What is a heterotroph?
This group of single-celled organisms consists of two domains, Archaea and Bacteria.
What are prokaryotes?
The study of the interactions between organisms and their environment.
This theory proposes that early metabolic reactions took place on rock surfaces near hydrothermal vents in the ocean.
What is the Iron-Sulfur World Hypothesis?
Processes that give rise to new species, building upon microevolutionary changes.
What is macroevolution?
Layers of tissues that form in animals during early development
What are germ layers?
This photosynthetic bacteria replenishes 50-75% of the worlds oxygen!
What are cyanobacteria?
Things that constrict the distribution of organisms.
What are limiting factors?
This group of animals have cnidocytes, or stinging cells.
What are cnidarians?
Groups of organisms capable of interbreeding to produce viable offspring.
What is a Biological Species?
Animals that develop mouth second
What are deuterostomes?
These diseases can be transferred between species.
What are zoonotic diseases?
Ecosystem stabilities are determined by this.
What is ecosystem complexity?
Species that have many small offspring and little parental care.
What are opportunists?
Speciation which occurs as a result of geographic isolation.
What is allopatric speciation?
While most animals have organized tissue, this simplistic group of organisms does not.
What is a sponge?
Prokaryotes produce these when environmental conditions become unfavorable for survival.
What are spores?
Roles an organism plays in an ecosystem.
When two unrelated organisms share a trait because they are adapted to similar niches.
What is convergent evolution?
Rapid evolution of a single ancestral species into a diverse array of descendants to occupy distinct ecological niches.
What is adaptive radiation?
This group of animals dominates the animal kingdom, with an estimated 85% of known animal species.
What is an arthropod?
Multi-layered sheets of prokaryotes held together by a gummy-textured matrix.
What is a biofilm or a microbial mat?
When two species interact and both benefit each other.
What is mutualism?
All chordates, including hagfish, have this feature.
Notochord!
