Evolution at a larger scale across many populations

Small changes across a population

Process for creating new species

A group of living organisms consisting of similar individuals capable of breeding/exchanging genes

Used to define what a species is

Characterizes a species based by body shape and other structural features

Group of organisms can potentially interbreed, or mate, with one another to produce viable fertile offspring

Prevents members of different species from producing offspring

Prevents mating and occurs before copulation

Species that occur in the same area, but occupy different habitats and rarely interact with each other

Species living in the same area that mate at different times of the day/year

When signals of one species are not recognized by another

Different in physical structures make mating impossible

When indiviuals of different species mate, but fertilization does not occur because of incompatability between the sperm and egg

Prevents hyrbid offspring from developing/breeding

Reduces a hybrids capacity to mature into a fit, healthy adult. Cannot survivie to maturity (miscarriage)

Hybrids are sterile

The second generation of hybrids reduce survival/frttility

Formation of a new species

When one population is geographically isolated form other populations

A population develops into 2 or more reproduvily isolated groups without geographic isolation

When many species evolve from a single common ancestor after they are exposed to different enviroments & resoures

Any group of individuals of the same species living together in the same area
