See, in 1996, two researchers argued that Lamarck, Darwin, and generations of biologists since had totally overlooked the main driver behind the elongation of the giraffe's neck.
To them, the particular form of combat that giraffes engaged in was the primary driver behind the elongation of their neck, with the ability to browse on higher trees being a side-benefit.
Over 7,000 human skeletons were discovered in the labyrinth, and some of the skulls have strange elongations and shapes, which have fueled speculation about the people who built and used this place.
According to an article published in the journal Science in 2016, researchers believe that sunflowers demonstrate this type of heliotropism due to their stems elongating at different rates at different times of day.
The cat, unnoticed, had crept up on muffled paws from Zeena's seat to the table, and was stealthily elongating its body in the direction of the milk-jug, which stood between Ethan and Mattie.
Seagrasses grow by extending a rhizome -- that is a subterranean stem that elongates at rates of about one centimeter to about five meters per year, and they branch and extend along the seafloor, forming large clones.
