🐸 7. The transition to land
The moment when life came out of the water and began to change direction
🌊➡️🌍 Life comes out of the water
About 370 million years ago:
👉 A huge change is taking place
🌊 Life in the water ⬇️ 🌍 Beyond the land
🐟 Beginning of the transition
During the Devonian period:
🦈 Fish with strong fins ⬇️ 🦎 Developing into limbs
👉 The beginning of amphibians
🫁 Breathing Challenge
In water:
🌊 Gills
On land:
🌬️ Lungs
👉 A fundamental change in the respiratory system is required.
🦴 New body structure
To live on land:
⚖️ Body needs to bear weight 💪 Stronger skeleton 🦵 Developed muscles
👉 No more water support
🐊 Transitional creatures
In the display you can see:
🦴 Fossils of ancient fish 🦎 Amphibian-like creatures 🌿 Wetlands and rivers
🧬 Tiktaalik – Connecting Link
One of the famous creatures:
👉 Tiktaalik
Features:
🐟 Limb-like fins 🦴 Neck 🫁 Adaptation for breathing out of water
👉 Connection between a fish and a terrestrial animal
⚙️ Evolutionary adaptations
The transition required:
🫁 New respiratory system 🦴 Customized skeleton 👁️ Air sensing 🚶 Ground movement
🔄 Gradual evolution
The main idea:
👉 Small changes ➡️ Over time ➡️ Create a huge change
🔬 What do you learn here?
The display highlights:
🧬 Relationship between structure and function 🌍 Adaptation to the environment 🔄 Evolutionary processes
🚀 Step into the journey
On the Astrogeonomy timeline:
👉 Step between:
🌊 Marine life ⬇️ 🦎 Terrestrial life
👉 Beginning of the land conquest
🔥 Summary of Showcase 7
This is the moment when life takes the big step — And come out of the water onto the land
