Question

What are some of the challenges that early aquatic vertebrates faced when they colonized land? What are some adaptations to these challenges?

Answer 1

The aquatic terrestrial veterbrates organisms occured in the Devonion Era and was an important step in the evolutionary history of modern land vertebrates. It waswa seminal event in the vertebrates evolution because it precipitate in the evolution of sudden radiation of species in the new land animals diversified in response to physical and biological conditions.

The first stage of environmental transition presented numerous challenges to ancestral acquatic organisms and changes in the morphological and physiological mechanism that underlie most life process.

The functioning of biochemical pathways, On land the water loss is a particular problem because water vapour pressure us much lower in air than in water medium. They can be categorized by two ways depending upon the fluctuations in available water

Most of the organisms can be colonised onto the land by marine and took place many times.
