Theory of Evolution Challenged: New Discovery Shows Terrestrial Plants Did Not Evolve from Aquatic Algae

A study in molecular biology by Danish scientists reveals that land plants did not originate from aquatic plant algae, specifically green algae, as has been traditionally believed by evolutionists. Instead, they appear to have different origins.

Jesper Harholt from the Carlsberg Laboratory, along with scientists Øjvind Moestrup and Peter Ulvskov from the University of Copenhagen, analyzed the genomes and morphological characteristics of green algae. They discovered that these algae were actually present on land long before the emergence of land plants.

Jesper noted that the hypothesis suggesting charophytes among green algae evolved into all land plants through a process of pre-adaptation is based on "too many happy coincidences." Their research demonstrated that the cell walls of green algae are too complex to have originated from an aquatic environment, which does not resemble the land environment.

Additionally, many green algae lack features typically associated with aquatic plants, such as flagella for swimming and light-sensitive eyespots. Therefore, the researchers believe this study challenges the theory that land plants originated from aquatic algae.

There are numerous types of algae, many being unicellular organisms, including most euglenoids (phylum Euglenophyta), dinoflagellates (Dinophyta), and some diatoms (Bacillariophyta) and green algae (Chlorophyta). Together with cyanobacteria, they form aquatic plant ecosystems.

Algae also consist of multicellular forms, such as all brown algae (Phaeophyta), most red algae (Rhodophyta), and many types of green seaweeds, commonly referred to as seaweeds, which thrive in marine environments.

For a century, textbooks have taught that all terrestrial trees, ferns, and flowering plants originated from charophytes within aquatic green algae. However, recent research suggests that some green algae thrived in mud hundreds of millions of years ago, indicating that land plants are not related to aquatic algae.

Jesper stated, "We know that algal cell wall complexity is very similar to that of land plants. This suggests that the assumption of ancient green algae being aquatic plants is quite curious." Additionally, other characteristics of algae imply that they had already adapted to life on land and are unrelated to land plants.

Algal expert Øjvind from the University of Copenhagen observed that the structural characteristics of algal cells do not support the view that all algae are aquatic plants.

The scientists explained that they could not find sufficient fossil evidence to support the concept that green algae evolved into all land plants, prompting them to look for evidence in the genomes. However, the results contradicted existing evolutionary theories.

Øjvind commented, "It's puzzling that if these green algae transitioned to land plants long ago, why do we observe so few of these green algae on land today?"

Peter added, "The genetic and morphological data we've obtained indicate that the traditional evolutionary hypothesis proposed by evolutionists struggles to explain the transition from aquatic algae to land plants. Therefore, we must reconsider our theories based on evidence from contemporary experiments."
