Based upon the study of layer of rocks

Does not tell the exact age: only compare fossils as older or younger, depends on their position in rock layer.

Oldest to most recent

Recombinant DNA is created by?

Central Dogma

Sedimentary layers are deposited

in a specific time

Youngest rocks on top, oldest rocks at the bottom

it states that the geologic feature which cuts another is the younger of the two features.

Layers of rocks deposited from above, such as sediments and lava flows, are originally laid down horizontally.

measure the physical properties of an object itself and use these measurements to calculate its age

a powerful and important process

it is a process that gradually selects the organisms that are better adapted to their environment to continuously change life

is not a finished event wherein humans are the final product.

Prevent fertilization and zygote formation

Allow fertilization but non-viable or weak or sterile hybrids are formed

Incompatibilities between egg and sperm prevent fertilization

Often occurs because the female immune system recognizes sperms as foreign and attacks it

occurs when two groups of organisms are separated by physical or geographic barrier

Differences in reproductive organs prevent successful interbreeding

Occurs when mating is physically impossible

Different groups may not be reproductively mature, making mating impossible

The evolutionary process by which population evolve to become distinct species. 

Process which new species develop from existing species

Hybrid fails to produce functional gametes

Occurs when two species that could interbreed do not because the species live in different areas

Two species life in different habitats – each is isolated from each other

Fertilized egg fails to develop past the early embryoning stages.

A hybrid individual develops but cannot survive to maturity

It may die before birth or reaching maturity

Patterns of courtship is different

Two organisms are able to mate and produce viable and fertile offspring

Occurs when members of a population that initially occupy the same habitat within the same

Occurs when the groups that evolve to be separate species are geographic neighbors

Match them

Who is the Father of Paleontology?

Who is the Father of Taxonomy?

states that in an infinitely large, interbreeding population in which mating is random and in which there is no selection, migration, or mutation, gene and genotype frequencies will remain constant from generation to generation.
