Origin of Life
The Línea de tiempo de la evolució begins with the emergence of the first simple life forms, likely prokaryotic cells, in the primordial oceans. This event marks the dawn of biological evolution on Earth.
Photosynthesis and Oxygen Revolution
Cyanobacteria developed photosynthesis, leading to the production of oxygen as a byproduct. This event significantly altered Earth's atmosphere, paving the way for aerobic life forms and marking a crucial point in the Línea de tiempo de la evolució.
Multicellular Life Emerges
The first multicellular organisms appeared, indicating a major evolutionary leap in complexity. This development is a key milestone in the Línea de tiempo de la evolució, setting the stage for diverse life forms.
Cambrian Explosion
The Cambrian Explosion represents a period of rapid diversification of life forms, with many major groups of animals first appearing in the fossil record. This event is a highlight in the Línea de tiempo de la evolució, showcasing the complexity of life that began to flourish.
Ordovician Period Begins
During the Ordovician Period, marine life diversified significantly, and the first land plants began to emerge. This period is crucial in the Línea de tiempo de la evolució for the establishment of terrestrial ecosystems.
First Tetrapods Appear
The transition of vertebrates from water to land occurred with the emergence of the first tetrapods, marking a significant evolutionary milestone in the Línea de tiempo de la evolució.
Permian-Triassic Extinction Event
The largest mass extinction in Earth's history occurred, leading to the loss of approximately 90% of species. This event reshaped the course of evolution, making it a pivotal moment in the Línea de tiempo de la evolució.
Dinosaurs Emerge
Dinosaurs became the dominant terrestrial vertebrates during the Mesozoic Era, marking a significant phase in the Línea de tiempo de la evolució, with diverse species evolving and adapting to various ecological niches.
Cretaceous-Paleogene Extinction Event
The extinction of the dinosaurs allowed mammals to rise in prominence. This event is a crucial turning point in the Línea de tiempo de la evolució, leading to the diversification of mammals and birds.
Genus Homo Emerges
The emergence of the genus Homo marks the beginning of human evolution, with Homo habilis being one of the earliest representatives. This event is significant in the Línea de tiempo de la evolució, as it lays the foundation for human development.
Modern Humans Appear
Anatomically modern humans, Homo sapiens, appeared in Africa, representing a major milestone in the Línea de tiempo de la evolució. This event marks the beginning of human cultural and technological evolution.
