Question

What was the first land animal on Earth?

Answer 1

Explanation:

The red algae called Bangiomorpha, dated at 1.2 Ga, is the earliest known organism that certainly has differentiated, specialized cells, and is also the oldest known sexually reproducing organism. The 1.43 billion-year-old fossils interpreted as fungi appear to have been multicellular with differentiated cells.

Answer 2

Answer:

• The world's first 3D reconstruction of a 4-legged animal backbone reveals that the first animals on land moved like seals.
• One of the studied animals was a fierce-looking, toothy beast known as Ichthyostega.
• It lived 374 – 359 million years ago and was a transitional species between fish and terrestrial animals.
