Brown et al. and Morwood et al. reported in 2004 that they had found skeletal remains of a previously unknown type of hominin, n
ow dubbed Homo floresiensis, on the Indonesian island of Flores. These hominins were small (approximately 1 meter tall) with small braincases (approximately 380 cubic centimeters) as compared with other hominins. The remains of H. floresiensis were found alongside handmade stone tools and the remains of dwarf elephants that also inhabited the island, suggesting that H. floresiensis was able both to make tools and to coordinate the hunting of animals much larger than itself. H. floresiensis is estimated to have lived at the site where the remains were found from at least 38,000 years ago to 18,000 years ago.
A large brain is not necessarily required for toolmaking.
What is toolmaking?
Making tools is done to manufacture equipment that aids in producing parts or goods. A toolmaker who has a thorough understanding of the product design develops components or tools that are employed in the production of the designs. To create, hold, or test parts or products throughout their production phase, it requires high accuracy and machine equipment. Additionally, because a toolmaker's work is unique, they frequently have to develop the unique tools or alter existing tools.
As it entails developing and the engineering tools needed for producing parts or components, the tool-making process is a crucial step in the manufacturing process.

The process of muscle contraction requires several steps.
The most famous theory on how the contraction and relaxation of muscles take place is the sliding filament theory.
However, this theory has been refined and one important addition to it is the mechanism by which myosin can pull actin and cause shortening of the sarcomere.
For the movement of myosin, it binds and releases actin and forms cross bridges.
Myosin is subdivided into two regions - S1 and S2. The contraction of the S1 region is what constitutes the power stroke.
An important requirement of the power stroke is the hydrolysis of ATP to release an inorganic phosphate which provides energy for the process.
