- Organisms adapt to evolve
- Worked on the behaviour of the progeny of racial hybrids
- Defined evolution as process of increasing complexity
- What drives Lamarckian evolution
- Can be made to show the relationship among the organisms
- The activities and behavior of ancient life forms left behind _ _ such as footprints, dungs, gastric stones, nests and burrows
- Study of the development of an organism from an embryo to its adult form
- Study of geographical distribution of fossils and living organisms
- Structures with the same set of bones that presumably evolved from a common ancestor
- Attributes that have lost most of its ancestral function in more recent species
- An important enzyme found in virtually all organisms
- Modification of the original theory of Darwin to remove its shortcomings
- Often credited with making the first large advance toward modern evolutionary theory because he was the first to propose a mechanism by which change of species might take place
- Which theory states that the giraffe ancestor lengthen its neck by stretching to reach tree leaves, then passed the change on to offspring
- Incorporates isolation as an essential component of evolution
- Programmed cell death
- Common structures are shared in the __ and disappear by the time the embryo reaches the juvenile or adult form
- Other term for cladogram
- Can be created to show the positions of the organisms in the evolutionary tree
- Two alleles for each gene separate during gamete formation
- Alleles of genes on non-homologous chromosomes assort independently during gamete formation
- In 1809, he published Philosophie Zoologique
- According to this theory, accumulation of continuous variations causes change in individuals to form new species
- Other term of Darwinism
- A highly-conserved protein which functions in the electron transport chain system of the mitochondria which is needed for the release of energy from food
- Example of evidence of geographical distribution
- Who states that some individuals born happing to have longer necks
- Proposed Ancestor of giraffes has characteristics of modern-day okapi
- After years of straining their toes to swim through water, these birds gained elongated, webbed toes to better their swimming. And wings of penguin would be smaller than those of other birds because penguins do no use them to fly.

- Theory that states over many generations, long-necked individuals are more successful, perhaps because they can feed on taller trees. These successful individuals have more offspring and pass the long-neck trait on them.
- The idea of "survival of the fittest"
- organisms best suited to their environment tend to survive and reproduce and thus become dominant.
- When reproductive isolation occurs, new species will form.
- Phenotypic variation exists among individuals and the variation is heritable.
- More individuals are produced each generation that can survive.
- It is the original theory given by Charles Darwin (1859) to explain the origin of new species.
- It believes in the selection of individuals on the basis of accumulation of variations.
- cannot explain the persistence of certain forms in the unchanged condition.
- It believes in the selection of individuals on the basis of accumulation of variations. Does not believe in isolation. It can explain the origin of new characters.
